This past winter I dropped in here to try out their tapas dishes. The staff was very friendly and make an effort to squeeze as many people they could into this small restaurant. We spent about 90 minutes here for dinner and found all of the food to be excellent. Although we did not find any problems with the portions I thought were a little small for the price. Just for future reference, I would strongly advise to find a table which is AWAY from the door. When we visited this place in the winter, we were literally sitting next to the door and felt the cold breeze coming through the door everytime someone entered or exited. I actually was forced to wear my jacket throughout dinner to keep warm.
To summarize, in order to enjoy excellent food and experience a very friendly staff, I would recommend sitting as far away from the door as possible during the winter.
