Here in Chicago we have a few bars that remind me very much of Spitfire - but I'm not sure any of them are as cool or consistent in terms of crowd, bartenders, beer list or loosey goosey smoking laws (not to mention cheaper).
That said, it's like a smaller, better crowd-having version of Delilah's with music like Cobra and bartenders like Kuma's. If I lived in Cleveland, this would be my bar. Period.
