Downtown Dining Week (in Memphis) is coming up in November. At the restaurants listed, they will offer a 3-course meal for $20.09 (corresponding to the current year). I've eaten at most of the participating restaurants, and they are all great. Great price too - doesn't include tax or drinks though, but it's still a great deal. November 8 - 12.
