We've just come back from CSR and I agree with Wayne, the breakfast buffet at the Pepper Market is well worth a credit! plenty of choice, we had a few where we 'ate as much as we could' but I couldn't eat like that every day!
They also have an eat as much as you like buffet for lunchtimes - can't understand why they don't do it for tea time too.
It was lunch we had, we originally planned on having a breakfast there but in 21 nights on DDP we only managed 1 breakfast at Tusker House, and that was only because it was all booked in advance. We ended up with the credits left over we were going to use at PM breakfast, I just can't eat in a morning.
Other than that I realy like the sandwiches at Wilderness Lodge.
I agree with a pp's suggestion of Wilderness Lodge. I really liked their breakfast waffle variety (DD had 3 Mickey Waffles with chocolate chips, strawberries and chocolate sauce, and DH and I had some kind with maple syrup, candied nuts and bananas, also orange flavored whipped cream - SOOOO delicious!).
For lunch, they had scrumptious sandwiches, and dinner had large portions of american food - flatbreads, burgers, etc. All was very tasty and filling.
When was the last time you went to the Pepper Market Wayne? There was a DIS podcast review of it that was scathing about the lunch there, because it has supposedly changed, which would put me off going.
