The Frisco Bar (www.thefriscobar.com) has "Cars and Cigars" every Tuesday PM. I haven't been to it before, but I'm planning on going tomorrow night. Probably at around 8.
I know the owner has at least one Lambo and Aston and one of the regulars also has a new Lambo. I've also seen a nicely kept Austin Healey 3000 there on odd days.
I've got plenty of Cigars for whoever brings their cars. Should be perfect weather for both.
