While visiting my family we had a great meal at this location (6 people). Parking was kind of a pain; the lot didn't seem built to hold the amount of cars that would visit this area. Also, if you never been there before make sure you use the stairs (or elevator) to get up to the restaurant. We were able to make a reservation and were seated immediately. Our waiter was awesome. Friendly service and very quick. No messing around. Your order and food keeps coming and coming. The drinks were good as well. Check out the menu. There is way too much to mention and everything was excellent on our visit. Here are some of the dishes we had, trust me, they were all great!
Apple and manchego salad
Sausage plate
Tuna peppers
Steamed mussels
Chorizo clams
Lamb skewers
Empanada
Crispy duck roll
It goes on....the one thing I did not like, but this is what you get at most tapas restaurants, is that the food is brought out so quickly, like an auto line. I feel like you can not truly enjoy your meal with so many people and so many dishes. You are rushing to eat just to clear room on the table. This is no fault to Firefly, it is now on my return list when I visit Vegas again!
