I love using Restaurant.com. Here it is, 80% off tickets the gift cert. price. Pay and print out the certificate, bring it in and bam, eats for cheap. Most $25 vouchers will be $2 after the code BLOOM.
Please read the restrictions as some places that accept the gift certificates have price requirements, but odds are, you'll get ~50% off your total bill. Like I say, good eats for cheap.
