I can not belive anyone from Pittsburgh has not posted yet.
Disney certainly does not have these:
Decent pierogies anywhere on site....
When you order a grilled chicken or steak salad in Pittsburgh it comes with French fries on the salad....
And lastly, one word Primanti's!!!! Where any sandwich you order comes with tomatoes, cole slaw and french fries ON the sandwich.. Hey Disney I am sure Primanti's would love to open a franchise location on property.......
I'm going to join you even though I am no longer from PA ... Southwestern PA food is the best!!! But you can't forget chipped ham, city chicken and halushki. We do pepperoni rolls too ,mmm. Unfortunately, I am not much of a southern cuisine connoisseur -- although DH is from Mississippi - so I have learned to make "dressing" not stuffing and some other southern food. As for Tennessee -- I agree that the Rendezvous BBQ is the best I've ever had but Corky's BBQ sucks, IMHO. My kids are really going to be messed up Italian/Slovak/and Mississipian, LOL. We are probably the only family that has catfish and linguini at the same meal. Sounds gross doesn't it?
I also had a deep fried snicker bar in Middle Tennessee -- oh my gawd -- best thing I ever ate.
I am originally from the Pittsburgh area--actually across the border in Ohio, and we always called it "chipped-chopped ham". I remember after I moved to Phoenix in 1985 I went into a deli and ordered "chipped-chopped ham" (having NO idea it was a regional thing.) The deli workers looked at me like I had three heads!

I still make halushki from time to time. I still make pierogies quite a bit--sometimes even from scratch--love 'em with onions...
Texas--our fajitas are just so good...they are just not the same anywhere else.
