I'm neither Mexican nor Spanish, but to me the food tasted very authentic and not at all tex-mex as I expected. The starter portions such as the empanadas and tortilla samples were very generous. You can stick with the traditional fair such as tacos and burritos but I highly recommend the main courses. I've dined here twice and tried the skirt steak pyramid, pork medallions, and sampled my girl's pepper stuffed with spicy beef. Each main dish was unique, flavorful and well prepared. The service was attentive and relaxed. Wait staff did not try to shove those $7 bottle water. On the weekends in which we dined, the restaurant was almost full but not crowded which made the atmosphere pleasant. Entries are sub-$20 coupled with the high food quality, makes Isla is one of the best fine dining values on the Strip. Its definitely a hidden gem among restaurants in Vegas. We will be coming back here again.
Pros: Very tasty food, not overly crowded, nice relaxed decor, excellent service.
Cons: There really is none that I can think of.
