I'm looking to buy a few restaurant.com 'vouchers' but I'm not sure I really understand all the smallprint. Any chance someone could decode for me?

For example, the Strip Steak at the Madalay Bay has the following:
Minimum 2 entrees. Valid with 2 Prix Fixe dinners
Does this mean 'only valid with 2 Prix Fixe dinners'? In which case, stating minimum 2 entrees seems redundant. Or is it valid with a minimum of 2 entrees, or exactly 2 prix fixe dinners, or 2 or more of either entree or prix fixe?

My other confusion is stuff like:
Minimum purchase of $35.
Does this mean a minimum purchase before or after the voucher has been applied?
