VillageVines.com has an interesting concept that has a bigger advantage for alcohol drinkers. Hybrid of a happy hour and a Groupon. The restaurants however set the time range that the discounts apply to bring in people during slower parts of the day. $10 dollars to reserve a table, and 30% discount is discretely applied to your bill.
I question how much one would really save due to the $10 fee. For instance, $60 bill with a 30% discount would be $42. Adding back the reservation fee of $10 puts the cost back to $52 and the effective saving is really only about 13% (omitted tax/tip which one would have to pay anyhow except it’s higher of course on a bigger bill).
