We only sat at the bar and had a couple plates before going to see a show, but I was really pleased with the experience.
The bartender was very friendly and attentive. He was very knowledgeable about tequila. The white sangria was delicious and fruity without being overly sweet.
The pan con manchego was absolutely perfect - great country bread, just the right amount of garlic and tomato, and very high quality manchego and olive oil. It was very satisfying.
The bartender recommended the wrinkled potatoes, which were deliciously salty boiled new potatoes with a delightful spicy dipping sauce. The sauce was very flavourful and had the right amount of kick.
Prices were very reasonable and portions were adequate, given that its a tapas place. Please run around $6-$8 for the lighter fare, and paella closer to $15 (I think) . Tons of great veggie options, which is rare in Vegas.
I'll definitely go back for a full meal in the future.
