The Merc Bar, Phoenix
The Merc Bar is on the upscale side, with its dark interior and leather booths and bartenders who will not offer you a drink menu (they can make almost any kind of martini but you have to ask for it). There's no sign outside that says "Merc", so you have to know where it is. But its not as stuffy as it sounds. Its still a fun place to hang out as the crowd is friendly and the drinks and music are great.
