Tonic

Huge menu of fantastic drinks. Very cool place, I wish there was more like it. Even though the oxygen made my nose runny, it was fun to try. Had one of the most delicious hot chocolates ever – «Mug of Love.»

The owner obviously has no sense of energetic or self awareness. He was rude and had no idea about sensitivity. Go visit shine instead as this store is spewing toxicity into the field. A huge bummer as I looked forward to visiting and ended up not purchasing anything due to the out of balance setting.

Great brews and elixirs. Friendly communal atmosphere. Seriously cold and closed off staff.

Really cool experience. Great drinks, nice people, low key vibe and cool art. A lot to love about this spot!

Awesome place! The elixirs and kefirs are fresh and delicious. Very relaxing little lounge to get your health on :) Knowledgeable staff!

Wow — I am glad I discovered this place. There may not be a more perfect shop for the Boulder lifestyle!
It is hard to tell if it is open from the outside, but once you step in, you walk into another world — natural healing lounge world. There are various couches and love seats and a ‘bar.’ There is quite an interesting crowd and very clearly many regulars… We set up shop at the bar.
As I was not feeling well, I really explored their various offerings — trying anything the ‘bartender’ recommended. I drank mushroom concoctions, inhaled scented oxygen, and took elixir shots. While I am not sure if it made me any healthier — I will attest to the fact that I left feeling super relaxed and at peace with the world.
If you are looking for a relaxing moment or evening and willing to try some über natural health products, there is no better place.
I look forward to my next trip!

Walked in with no greet and weird vibes. I’ve studied herbal medicine and been to many tonic bars also worked at Café Gratitude for two years making many tonics and elixirs. I don’t care if you have good quality if your customer service is bad, you create that reputation. The vibe I got was not welcoming. For that reason I will not return. If you want good vibes, maybe it was just a bad day for the guy who was working, even then I still cannot recommend it.

If there was one place on Planet Earth I could pick up, put in my pocket and take with me everywhere I go as a place to relax and enjoy great company, undoubtedly it would be Tonic Herban Lounge in Boulder, CO.
The owner Mark is not only one of my favorite humans of all time (and I know a LOT of them, so that’s saying a lot), but the vibe and the clientelle at Tonic are the bombdiggadddy. Conscious, cool, hip, educated, well spoken, and always with just a sweet touch of fun sacrcasm that I personally love, Tonic is for me a place that the world needs a whole lot more of
Thanks Mark for your years of ears, heart and service to Boulder, I wish you’d come to Miami. I need you.

There should be more of these bars across the USA! The world! I love how kind and friendly the bartenders are and how well they serve up the elixirs. Thank you Tonic!

Absolutely in love with this place. We just enjoyed a Kefir Elixir that helps with digestion. Mine was with Tumeric and my friend Geri, had a Berry Blast.
Now we are enjoying 20 minutes of Young Living Essential Oil Oxygen. Mine was for Energy and my friend Geri chose Release. Stay tune as we relax and enjoy this amazing treat.

I love coming to Tonic! A true oasis in Boulder. Mark the owner and bartender is a such a gem. The menu is epic and I feel grounded and full of bliss every time I leave.

This place is really interesting! I’ve done the oxygen bar and a kefir cocktail. It was super relaxing and a really nice place to just hang out with a couple friends. Will be coming back for sure!

Fun, little hippie joint in Boulder. Go for the under-​the-​tongue tonics (they come on a tiny spoon and burn for 2 seconds, but make you feel great!)
Definitely a side street hidden gem in Boulder. I love to meet a friend here for a chill night or a great cup of fresh Kombucha.
Service is a bit slower, but who cares? That is supposed to be the vibe here… no one is in a hurry and it’s kind of nice.

The best place ever to get a healthy high! My favorite indoor local hang out.

Last week was the first time that I have visited an Elixir bar in my life. If, even 24 hours before, you had told me that I would find myself sitting at a bar that served oxygen and $ 7 kombucha, I may have smacked you in the privates. However, for whatever reason, there I found myself running up a tab and feeling good about it.
From the outside it’s hard to tell what this place is. Sure, there’s an A-​frame right by the front door, but it’s barely noticeable especially if you’re in Pearl St mode. This made it a bit hard to find, but I’m glad because this means that others will find it hard to discover as well. The more people that discover a place like this, the less I want to go.
I used to go to alcohol bars and run up tabs in the triple digits, which is what I told myself made it ok to go enjoy a couple pricey yuppie drinks at Tonic. After one visit and two drinks, I’m hooked. I have recently quit drinking alcohol and have been looking for places to hang out by myself where I don’t have to get wasted. Coffee shops are ok, but I can only handle so many cups.
I had some kind of happy drink and an absinthe and left Tonic only $ 13 in the hole and feeling like I was floating on a cloud. Although I can’t bring myself to pay for oxygen (maybe one day when I’m drinking again and feel hungover), but there is no doubt in my mind that I’ll be back to Tonic.

Way Too Cool! This was perfect for coming from a low altitude. We felt like heaven!

Tonic is a nice little relaxed lounge. With ambient music, rock fountains, delicious herbal mixes, it is one of the best kept secrets of Boulder. A nice date spot.

I really struggled deciding between 3 and 4 stars on this place.
Vibe: Yes, this is total hippy/​organic type place. Personally, I think the general interior is quite charming with unique art and attitude. With that said, small seating space and tight quarters during any live sets make this place too crowded for comfort. 4 for coolness; 2 for tight spaces
Service: slow and not well-​staffed in my experience. They were definitely not efficient and I would definitely recommend that the servers hold off on the cheeb before they get to work. 2 stars.
Menu: I really liked the offerings as they were unique and tasty. I really enjoyed my crazy beverage that had all kinds different additives and anti-​oxidants. I also liked the oxygen bar. yes, it is pretty hippy foo frro but what the hell – it was fun and tasty. 4 stars.
Overall: I liked the place and I would recommend it for couples or dates. I would avoid nights where they have special events or going with children as the cramped nature of the place and slow-​footed service will drive you batty.

IMHO, Tonic is the best kept ‘secret’ in Boulder. With the slogan «Embrace the Unknown» that’s what you do when you enter Tonic. If you like a place that’s different, real, healthy, alternative (in a classy way) and chill, Tonic is for you.
Offering everything from teas, potions, smartinis, their specialty Juns, organic wine/​sake/​mead, oxygen sessions, herbal elixirs, raw food, snacks, superfoods, amazing desserts and more, this place is literally a tonic for alleviating your stresses, your hunger, your thirst, and your desire to connect with really interesting, genuine, warm, friendly, aware, health conscious people.
Tonic also has live music, DJs and performances — you can follow Tonic Herban Lounge on Facebook to get updates on what they have on each week.
I always wanted to find a local lounge that was open late at night and where I could relax a mature, cool crowd, enjoy great drinks and chill music (and not be filled with students/​drunks). Then I discovered Tonic… The ‘Relaxosphere is open for blissness’ from 1pm every day until 11pm (sometimes later if it’s busy) seven days a week, so it’s the perfect way to start or end an evening. With free wifi, you can also use your laptop and work, which I often do…
The ambience can’t be beaten and the owners, Mark & Heinz offer wonderful, warm helpful service and often sit down to connect and have a conversation with the patrons. There are lots of regulars (of which I am now one) — I come here almost every day now. and no, I don’t work here! LOL
My favorite drink on the menu is the «Inner Sanctum». Also be sure to try one of the amazing desserts (whether you are raw, vegan, or not. you will find them delicious.
For something different, or to help with the altitude or to shift your energy/​mood, the oxygen is great. I don’t do it often but it really does help a lot if I have had a challenging day and need to relax and shift my attitude. It always perks me up. Don’t ask me how it works, but it does.
I also laughed at the negative review by Grzegorz… definitely not the kind of person that frequents Tonic. It’s not a place that attracts drinkers, negativity etc. It’s probably the kind of place you either love or hate. The people that come here about love — and you can feel it.
I’d say simply keep an open mind, be willing to try something different, embrace the unknown and try it for yourself. If it doesn’t resonate, there are plenty of other bars and places close by to go. If it does, you’ll appreciate what a unique and special place this is, and will want to keep on coming back.
I only had one reservation about providing this review for Tonic — and that is a little part of me wanted to keep this place a secret little sanctuary and not tell anyone about it. But I do think it’s the kind of place that everyone needs to experience, if you feel drawn to anything you have read in these reviews.
If you need to soothe or feed your soul… you won’t want to miss a Tonic experience.
PS. Tonic does not allow children, so can’t rate it as family friendly.

Original owner, Mark, has returned, and that is great!
This is a pleasant and deeply relaxing place to rejuvenate and re-​energize! Nice selection of raw food desserts, too!
Attentive service.
I still can barely tolerate the parking situation in downtown Boulder. That’s the only downside for me. Next time I’ll take RTD or ride my bike!
