We used the $25 coupon last month. 2 ladies, no kids with us. I cannot remember but I think we both got burgers, sodas, and split a dessert? wish I had a better memory, but I think we were just over $50. We thought the food was very good, and it had a nice atmosphere. So $50, less $25 coupon, add back tax and tip, it was still about $35 for 2 adults.
To be honest, the place seems overpriced and the coupon does not make it "cheap", it makes it reasonable. But, that said, it is a good deal, you are still getting $25 off. It is so convenient, being right at DD. We were staying at the Vilas at Grand Californian. Everything is so close at DL, you could leave one of the parks to eat here.
I bought some of the $50 coupons, but I regret that. 3 of us are going in August, I am not sure 3 women could hit $100, we would have to eat alot or order big steaks, etc. (at the time I ordered them, I did not understand the $100 minimum)
