Last night, I had dinner with a friend who's a member of Passport Unlimited (http://www.passportunlimited.com/more_info2.asp?info=dine). He showed his card and we got one entree for free.

Looks like they have three types of memberships, priced from $87.50 to $145. There are some kinds of poorly specified "travel" and "lifestyle" benefits included as well, but I'd only be interested in the dining benefit.

Does anyone use this service?
