This tip from Citysearch's Go e-mail was too good not to repost:
EAT
Cheap MF Eats? This is not a typo.
MF Buckhead is considered by many to serve the best and most elegant fish in town, but is also known for being wildly expensive. Grab a $20 lunch (3 courses) on weekdays before 2pm, or an early-seating special of $45 for five courses before 7pm every night.
