I'm hoping this trip to visit Pinocchio Village and hopefully Pirata/Perico will be open. But I always love the burgers at Peco's Bill just too much to eat in one week!
The reality is that I don't think any counter service at MK is so much better than the others that it is worth going across the park for and it's important to get lunch in by a certain time.
Ray's probably has the biggest selection. But we like certain items at all of them.
What we do is our first try is the place closest to us. Our back up is always Columbia Harbor House because it is more centrally located and less crowded than most and you can always get a table upstairs. We also try to get to the lunch counter by 11 am.
Another vote for Columbia Harbor House. Although DH and I really enjoyed Pinochhio Village Haus this last visit which we had not dined at since the kids were little. I had a very tasty turkey panini sandwich...and the fries were very, very good.
