Location location location. This place is a total dive, featuring what I think can best be summarized as 'truck stop chic' - but it is located just off the strip behind the Flamingo. With drinks at the bar of your typical club running $8-12, the thought of a little in-room pre-gaming isn't bad. And Stage Door knows it.
Smaller bottles are of most liquors are about $12, while a standard sized bottle is about $25. Big bottles are over $30. Red Bulls are $3 each and half a gallon of orange juice is $5. Yeah, they're gouging you, but it is still cheaper than going out.
If you're nearby, at Ballys, Caesars, or the Flamingo, definitely worth going to...unless you can find another place.
