I'm a fan of this place in Indy called Chumleys Grill. It's 21 and over, but they serve food so my parents just think it's a restaurant that I go to a lot when they accidentally open my credit card bills.
It has pool tables, big screen TVs and the best bar video game ever, Golden Tee! It's not really a sports bar, but they always have the Cubs game on and it's kinda like Cheers, except darker.
Now if I could find a place like that in Cincy which wasn't all 40+ I'd be happy!
