Arrived there on a night of live music and it was probably the best evening we had in Granada. Great music, fantastic ambience, there was some salsa dancing going on. Great location and decor.
The food was delicious, greatly presented, we had fish which is always a bit risky but it was great, fresh and delicious. We also had the dessert, the mango bread, which is their awarded dessert - and the only one on the menu. I do agree though that it is very overpriced. 15 us for a dessert is quite a lot.
So in a nutshell, do go and splurge, great atmosphere but expect to dig a bit deep at the end in your pockets.
