Think of it this way. It's roughly $40 per person. One sit down meal with dessert and drink is going to cost you about that much, IF you're buying all you can I guess. Like choosing filet mignon instead of a chicken breast sandwich
For example, a dinner at Le Cellier:
Filet Mignon - $27.99
Chocolate Whiskey Cake - $7.99
Soda - I don't know the cost on that one.
and sales tax has to add up to at least $39
So that leaves your CS and snack basically for free.
Now if you go to a cheap TS and you eat food that isn't expensive then yeah, it wouldn't be as much of a deal. The way I'm looking at it when we go is that I actually get to order whatever I want off the menu without worrying about how much it costs and if I have enough money in my account to cover it
