I was contemplating also doing this and did some research. It appears that the restaurants/counter service included are the least liked of all the eating establishments, at least that is the consensus. I personally have had luck at Mel Diner's we had burgers there no better or worse than I'd say the local McDonalds. I've had a good burger at Burger Digs we got there and they were just making them so not sure if that was reason for this, but again, not the best or worst burger in the world, it subsided our hunger and we didn't get sick, we just wanted something quick and this served our purpose.
According to what is written on these meal deals you have UNLIMITED access to the select food venues so if you are traveling human trash disposal (as I refer to my teenagers) then this could save you a bundle. If you are traveling with picky eaters than it wouldn't be that much of savings since the meals themselves are not that expensive if you only have one, once you venture into having more than two meals per person, it would be worth it. Be aware that you cannot take food out of the restaurant and sharing is frowned upon (even though I can't imagine how they would be able to control this, but it is stated in the rules).
The one thing I'm interested in hearing about is whether anyone has gotten the meals with CW add on, its only $5 for a dinner entree at selected locations in CW. I'd like to hear someone has faired with that. Hopefully, others will chime in and give some more info on this. HTH
