I do like this restaurant, but I am not sure what the big hype is all about.
The food is good but in my opinion the taste is not worth the price. There is just nothing about the flavor that makes this restaurant stand out. So either every time I have gone there I order the wrong things (doubtful) or there really is nothing that stands out about their food. I am from the Netherlands, which is not too far from Spain (where everyone always goes for vacation), and have had amazing Spanish food before that the food at Firefly's does not even come close to measuring up to.
The only thing I have had that I would ever go back to eat that is completely worth it is their ribeye entree. Makes up for all the other dishes, like the flavorless paella.
Other than that the restaurant is beautiful and upscale compared to the average restaurant. Perfect place to take a date for the second or third time (might be too expensive for the first if you are a poor university student like me) or to have a dinner celebration. The staff was wonderful.
If you are just looking for a good eatery and aren't eating out for any special occasion, I probably wouldn't suggest this place.
