I posted this info in that Prom thread, but here it is for the general public:
If you want to save some cash when dining out, go to restaurant.com
and enter your zip code. Find a suitable restaurant (Like Il Lupo in Fairfax). The restaurant selection is kind of meager, but whatever.
When purchasing your dining certificate enter Promotional Code: 66289
That code is good through 5/1/05 for 50% off.
Hence, you can get a $25 meal certificate for $5.
Be sure to read the rules b/c many restaurants won't let you use it on alcohol or whatnot.
FYI: I got this info from fatwallet.com
