I can’t believe this place hasn’t been reviewed yet! We’ve been here a few times, and actually purchased our first bottle of oil yesterday. It’s tucked between Rappahannock Oyster Bar and Lyon Bakery, and across from DC Empanadas in Union Market. There’s usually one person working there. I’m not ire if he’s the same person, but they are big into customer service, so if he’s helping someone else — be prepared to wait a few minutes — I promise you, it’s worth it! All of the oils seem to hail from California. They have your standard EVOOs to some interesting flavored ones. The one we left with was an oil and balsamic mix with Italian herbs and spices. Delicious! You can try most of the oils too, which is great. We paid $ 20 for the bottle, which I thought was reasonable. We’ll probably use it for a long time. They also have cute little packaged mini oils that would make great gifts. Another great addition to Union Market — I am a fan!
