Oh my goodness ... this thread has made me think about all the local food I haven't been able to eat in a while, but will surely miss!
I'm hoping these images work ... Buffalo has the wonderful "Beef on Weck"

Ted's hotdogs:

and of course the best wings ever (which I can eat, and will be bringing Frank's hot sauce with me!).
... Can you tell it's dinner time for me?
Glad to hear there are so many hot dog options for holidays to remind me of home! Hopefully some are also GF (they should be, but I never trust the UK to not fill things with bread crumbs).
