Where to write late at night?

I like to write after I get off work at Starbucks between 11 and 11:30pm and I am getting kind of sick of Waffle House on Tunnel Road (even they are really cool and nice). Can anyone think of somewhere else that might be open late and friendly to a writer (and preferably has a smoking section but not required)? I don't need power outlets, just somewhere to park it without spending too much money.

Thanks!
