Came to Vegas for a Trade show and had the opportunity to check out the Firefly. WOW! If you don't even know what Tapas is, you must begin your food education here, for this is by far is the best Tapas restaurant in the States that I have have encountered. Lots of vegetarian dishes as well, but do try the filet mignon sliders.....to die for. Great service as well, being close to the Las Vegas Convention Center the staff is well seasoned, however, it does get packed when a show is in town . They do take reservations.
