I was lucky enough to be a part of a private wedding party at Firefly last week. Holly mother of all that is awesome this place is great!
The atmosphere is Vegas lounge-esk and lets you sit back and relax while you're served tapas and drinks in a club like environment.
We sampled almost every plate they offered throughout the evening and I was never let down. The stuffed dates will be the last meal I have before my dirt nap...seriously they were that good.
The staff was super friendly and the bartenders were well trained. The blueberry vodka mojitos are incredible despite them being anything close to a traditional mojito. Nothing but love for this place and it's staff. You have to go here while you're in Vegas.
