We were here on a Saturday night and luckily enough, quite early, just before the crowds came and people had to wait at least 30 minutes for a table.
The food is very, very good and the prices are very reasonable. We had two starters (the champinones and patatas bravas) which were both excellent, although quite heavy on the garlic ;-) the pizzas are absolutely fantastic, both crust and filling. Some of the best we have had outside of Italy. The desert, a chocolate mousse, was decent. With this we had 2 beers each and a cappuccino, all for around 130.000 pesos, or 37 euros. Excellent value.
The atmosphere in the restaurant and the music really adds to the overall feeling. There were some other tourists, but about 80% of the clientele was colombian.
Very nice experience, would definitely recommend it!
