1. 50s PTC is tops on my list. Love the nostalgia here. The food is always good, and I enjoy the variety as I tend not to get set on just one dish here. I always save room for a PB&J milkshake and I never, ever order dessert out, so this is unusual for me to make sure to get. Also, when the servers are on cue, I love the antics, and I like to engage them in conversation to be this way. We have been almost every trip since 1999, and we have been at least 35 trips! So thats a lot of 50s!!
2. San Angel Inn is another must do for us. We love Mexican food and this isn't your neighborhood Tex-Mex place, far from it. Its more authentic, and you need to be prepared for that, but in a good way. Forget the typical enchiladas, tacos, etc. Branch out your pallete and you will be surprised at how good this place is. And the atmosphere, its #1 for me on property.
3. This is hard for me because we love so many places at WDW, but at this moment, Rose n Crown tops the list. Love the food and the atmosphere, and really enjoy talking with the CMs. We visited England a couple yrs back and find it interesting to get the lowdown on where the CMs are from, how they like the states and WDW, etc. But this is one of the only places we really enjoy the apps and if room allows, the desserts.
I have to throw out a honorable mention(in other words, can't just stop at 3
The Wave has great breakfast buffet and lunch, don't do dinner, not as good, but the 2 other meals, spot on good and a great respite from MK, just a few steps away.
