I ate here twice while visiting Las Vegas, NV. I love the prices. The quality of the food is quite good. I enjoyed the flamenco paintings on the wall and the atmosphere afforded by pleasant waiters reminding me of southern Spain. The tapas make me happy. The only thing I would add is some more architecture...as it is, the place is a bit too much of a strip mall in a desert city in the U.S.A.. It needs a bit more stone work, a tighter decor that makes you feel like you are in a tiny alley in a historic town in Andalucia. Oh well, it's Las Vegas. Go for the prices and you won't be disappointed by the food.
I guess the "firefly" lived up to it's name: the place needs to add some fly catchers on the front patio.
Another recommendation to improve this place would be a better beer list. More microbrews from the United States would be a good addition to the Spanish wine drinks.
