Porteña

A four star really but since they are one of the only stalls open past 5pm during the week, they get a full extra star.
Directly across from the Market Porter, a super busy pub every night of the week, you can get your post-​work pints AND a decent dinner you can eat on the way to your train.
My experience with empanadas is entirely Mexican based, and these are basically the same: are hot little pockets of deliciousness you can eat on the go.
The steak and spicy chicken are excellent quality for the traditional versions but they have non-​traditional (and vegetarian!) options such as — my favorite — carmelised onion with cheese and spinach and ricoota.
They have beer and wine for sale too so you can get drinks and eat your empanandas at their terrace seating (which is covered and has heat lamps in the winter).

Argentinian Steak sandwich. Good chimichurri sauce with it. Will come again for sure.

One of the best place where to eat empanadas in London in pure argentinian style. And the beer too, of course.

It was lightly raining, but under the heated canopy I warmed through nicely having yet again not dressed warmly enough to see me through a spring evening date.
It’s a cozy spot outside at 10pm, nothing like the circus that Borough Market is during the day. On a Saturday night, it’s perfect for a pit-​stop, everything you want out of a street food stall, gently bustling with a few couples feeding each other steak sandwiches.
The pastry was light and ungreasy enough to not need to reapply my lippy after eating, but I can’t guarantee how the evening may go. It won’t be the empanadas fault if my lippy doesn’t last but Maybe (line) it will.
Good girls have a sit down empanadas with a glass of wine in Borough Market. Bad girls have it’s less sophisticated equivalent; a Cornish Pasty at London Bridge after too much wine and missing the train.
Very bad girls have wine, epanadas, light frothy cold beers on a date that may not turn out to be a waste of make up, miss the train and still seek out the beacon of the pasty stand.
I started out as girl number one at this warm lit open place but as the saying goes: Any Porteña in a Storm!

Favourite stand in the borough market. The empanadas are great, especially the beef and jamon y queso
The steak sandwich with chimmichurri (sp?) takes me back to the parillas of Buenos Aires.

In our new place, we are lucky enough to live just a short stroll from Borough Market. Last week, we decided to check out some of the late stalls for a nice dinner outside in the lovely weather.
Portena offered a taste of Argentina, but despite their efforts, I was slightly let down. The empanadas were avergage, with the spinach and cheese being the best, but I found the pastry was just too thick and made them feel a bit stodgy and dry. My steak sandwich had a great piece of juicy steak, but the bread just didn’t seem right, a bit too flaky and became soggy and made the whole thing pretty difficult to eat.
Three stars, mostly due to the wine (which was delicious) and the ambiance of the market!

Extremely tasty filled pastries (empanadas), the environment is cozy and the ladies are very receptive. If I were Argentinian I would definitely feel at home. Just one thing that caught my attention, with the hand they give you the food, they use also to handle cash, not the ideal way of handling cash and food.
Overall, it’s definitely a place that deserves a visit.

Ok empanada. Dough a bit of a let down and meat mixture salty and tasted of «seasoning.» That said, ate the whole thing and enjoyed it — not an all star empanada but entirely worth trying.
Cool that London has south American food though.

Born in Buenos Aires but Baked in Borough Market– this is Portenas tag line and they seem to be moving up in the world. Formerly a stall under the train station in the market, Portena have recently moved to a larger retail unit opposite the Posh Banger bros and Monmouth Coffee co. Try the Beef Empanadas, small but superb!
