this forum may not be for this, but i'm pasting some of the terms & conditions according to restaurant.com:
• Limit one (1) redemption per party, per month, per restaurant.
• Limit one (1) Restaurant-Specific Certificate per redemption. Only one Restaurant-Specific Certificate can be used per party, even if the party is seated at separate tables and/or receives more than one check.
• Valid for parties of two (2) or more unless otherwise stated.
and skipping to the last term:
• With 50% OFF certificates party size may not exceed 8 people.
if not exceeding 8ppl might save $.....
