Do not enter there if you want the thrills and fuss of a high end restaurant. The decor may even rebuf you. But I advise that you pass over this. Normally, the food will make up for the lack of decor (even though some improvements would be welcomed).
This was out first night out in Barcelona after our flight. We just walked in, after I checked the reviews on Tripadvisor. The restaurant was fully booked but they have a small bar area where 4 people can sit. My wife and I sat there and basically had the area for ourselves with a very nice waiter that took the time to help us make sense of the menu. He recommended local dishes and even suggested half portions (not trying to oversell to us tourists!) so we could try a bit of everything. We had a great evening...enjoying the talk and the food.
We saw plenty of locals coming in - a sure value here. The place is clean, the food was good, people are nice and the price is right!
Again, not a 3 micheline wanna be restaurant. But I do not think you can go wrong.
We liked it.
