On several previous trips to Vegas, my wife and I have enjoyed Mermaids.  Deep-fried twinkies/oreos, cheap slots, and fast/friendly cocktail service.  During our last visit on October 1, we were told by a large, German-esque waitress that we'd have to both be playing at least $5 minimum to get service.  Um, haven't had to do so in the past, and after her treatment, the next 2 or 3 servers sure didn't mind taking care of us.  So, either the first waitress was wrong/cheap, or the following were being too free with Mermaids' beer.  Either way, we ended up having fun, and the twinkies/oreos are still worth the visit.  As for German-esque waitress, I hope she didn't mind not taking our tips.....
