No tables in ESPN Zone. There are a few poolhalls in the Baltimore Metro area, for 9ft tables there's Runnin Out (sp?) in Dundalk, MD (about 15 min or so from downtown) TopHat Billiards, not sure of the address but you can google it. There's usually some pretty good action in both bars in the weekends and evenings.
For barbox pool, there's The New Green Room in Dundalk (about 15 min or so from downtown) they have 28 bar box tables, all in really good shape and the food is good and the beer is cold!
There's also Cheers right off of 695 in Bel Air, MD. It's gonna be about 25 min or so from downtown but I've heards it's nice.
There are several poolrooms within 20-25 min from downtown.
There used to be a poolroom downtown called Edgar's but I think it closed down some months ago.
I'll send you a PM with my number, give me a call if you're in town and we can hit a few spots if you want.
