Thanks for the link Mike. I know the Original Pancake house from my brothers. There was also one in suburban Seattle.
I've had Dutch Babies here in New England. There is a place - Bickford's Pancake House - here in New England that is known for them. I think Bickford's is mostly in Massachusetts and New Hampshire.
My mom used to make German pancakes which, I think, are similar and probably easier than regular pancakes if you're feeding a crowd. She would make a couple in pie tins in the oven instead of standing in front of a stove.
