I've been meaning to check out this joint since it opened and am overall very satisfied with my dining experience at bar begonia. In my opinion, it has a very similar vibe to black hoof or bar raval...good drinks, tapas style dishes meant for sharing, small intimate space...just a good place to drink, chat and snack away. I don't think they take reservations so there might be a bit of a wait at peak hours and/or on the weekend, especially given the size of the place. We were able to snag a table for two on a friday night around 7, but by 8:30-9 there seemed to be a few groups waiting for tables.
Our server was very friendly and helpful with recommendations and also very knowledgable about everything on the menu. We ordered a couple of dishes from each section of the menu and I would say that there were a few standout dishes but the rest were average. My favourites were the gougeres, sardine tartine, salami savoie, and the chocolate ganache dessert. I think my least favourite dish was the duck rillettes. I've heard many people rave about the beouf bourguignon but I honestly thought there was nothing special about it. It was tender and nicely seasoned but I've made braised beef at home before that tasted just the same. I didn't find it to be a standout.
We ordered beer and wine so I can't comment on the cocktails but I will say that the bar was definitely poppin.
I would come back for drinks, the gougeres and tartines.
