A lot of Bama fans are meeting at STATS Sports Bar to watch the early games and listen to the radio stations who will be doing live feeds. Every one I've talked to said it's an awesome sports bar close to the Ga Dome. You may want to make reservations though. Ask for the table with the built in beer taps.
