As you may have figured out by now, I live in the New York City area. I suspect that NYC has the highest concentration of Disney restaurants that are not actually in Disney World. So if you're missing your favorite dish from Orlando and you happen to be in New York, you still might be able to get it (or a close approximation of it). Let me take you on a brief tour....
If you love Baby Cakes in Downtown Disney, you can always try the original Baby Cakes on the Lower East Side. Here is Part IV of my epic taste test.
If you love Earl of Sandwich in Downtown Disney, you can hit up Earl of Sandwich in Midtown West. Here is a post on one of my visits, with links to prior visits!
If you love schoolbread from Kringla Bakeri in Epcot, you can check out Bakeri in Brooklyn. Here is my recap of their schoolbread! If you're just in it for the name, there's always Shoolbred's pub in the East Village.
If you love Shula's at the WDW Dolphin resort, you can make a reservation for Shula's in Midtown West.
If you love Il Mulino at the WDW Swan resort, you can call for a table at Il Mulino either uptown or downtown!
If you miss the okonomiyaki they used to serve at Katsura Grill in the Japan Pavilion in Epcot, try Otafuku in the East Village (mine were covered in bonito flakes and came with tako balls but you can get them sans bonito and sans tako (but you'd be crazy then because: delicious)).
What Disney eateries have you found in New York? Or in your own hometown?
