Here is my take on the vouchers. You only get a good value at some of the places to eat, not all of them. We use the Q & C vouchers at Pepper Market and Beaches & Cream. For example at PM we have gotten the Ribeye Steak--comes with 2 sides, a drink and a dessert. We paid $11.25 for the voucher but on the above mentioned meal the steak is $17 alone, plus $2-3 for dessert and about $2 for your drink. You are coming out ahead on that. They also have fajita's that are $11 and quesdilla's--about the same $.
We use the $30 lunch vouchers at Rainforest Cafe only. You get an appetizer, meal, drink and dessert. But believe me this is a lot of food--enough for 2 or 3 people. So when you share the meal that makes it a good value. If your just going for a burger it wont save you any money.
