Unlike candy bars, which have decidedly shrunk over the years while their price has risen, hot dog size has always been all over the place. For the most part hot dog joints have always served anything from 12 to a lb. to quarter pounders. It's the price that has changed.
That's why a good report on a purveyor of the frank must include size, as well as method of cooking, dog brand, ingredients of the weenie (i.e-pork, beef, both?), type of bun (steamed, toasted, or other, and is it a good match for the dog?). Don't just tell me they have great toppings and you like the paintings on the wall. While I like all that, I'm more concerned with the important stuff here listed, and then the cleanliness of the bathroom. If the bathroom isn't clean, where you have access, gosh knows what the preparation area looks like.
The best advice, if you like the dog but find it a bit small, is have two, or three, if that's what it takes to create the nostalgic feeling you seek. And if it means not giving Mr. Fields his rent that week, maybe Hillary Brooks has a cousin who can loan a fellow a few bucks.
