Cato's Ale House is a pub on Piedmont Avenue. They've got a good beer selection, decent food (last I tried it) and a good overall vibe. It can be a little dark given the lighting and dark wood interior, but the front area overlooking Piedmont Avenue is a great place to spend some time with a beer.
They may still be holding weekly trivia nights- best to check!
They're owned by/affiliated with the same people who own Ben & Nick's on College Avenue.
