Cesar on Piedmont, after 10pm Sunday and Tuesday-Thursday everything (?) is 20% off. Also, they now open for breakfast or brunch at 8am, and are closed Mondays.
Adesso has its free appetizer spread during the last hour of business, which last I checked was 10:30 to 11:30 Monday through Wednesday, 11 to midnight Thursday through Saturday.
Spenger's, I'm not sure this is current but they were doing food and drink specials including a $1.95 burger Monday-Thursday after 9 and Friday after 10.
