Revolving Door is a speakeasy-ish, dive bar-ish cocktails bar on out-of-the-way Hefei Lu. A disappearing breed — it's actually in a converted residential house — Revolving Door offers up everything you could ever want or need of a bar: really good, heavy drinks and a room full of interesting people to drink them with. A two-story house, the first floor is the cocktails and the second is a cigar-smoking den. On the menu is a collection of classic cocktails on one side, the in-house variations on these on the other, and then a bunch of seasonal, summery stuff thrown in. Easy enough.
