On a random Tuesday evening I found the following at Firefly:
Attentive & pleasant servers.
Good food.
Lively (yet not whooped-up) atmosphere.
Most excellent Happy Hour prices.
Its located off-strip; a mix of locals and visitors.
The soundtrack was Thievery Corp.
It started to get slammed around 7:00p.m.
Five stars for realz cause its pretty close to a "normal" urban experience as I've had since relocating to Vegas from Seattle last Oct.
