Great Route. I think there was a similar thread about this once. you may want to check.
Anyways, US 20 through the Finger Lakes is my old stomping grounds. It joins NY Route 5 just east of Auburn and locals call it 5 & 20.
East to West:
Skaneateles:
Doug's Fish Fry. Fish Fry rules, but Doug's also sells Syracuse's famed: Hofmann Hot Dogs. So, you have your choice there.
Auburn:
Curley's Restaurant: A local favorite - mom and pop italian, the pizza and wings were a favorite happy hour tradition.
Reese's Dairy Farm: A good old fashioned ice-cream drive-in.
-----------
Between Auburn and Seneca Falls
If you head south on NY Route 90 to Union Springs, right before town, there's a roadfood stop on the right that sells hotdogs, burgers and such. My former students used to work there when they were in HS. It's a seasonal stand, and the chili dog is pretty good. It's about 8 miles from US 20.
----------
Seneca Falls:
Downtown Deli: What a NY Deli should be - for Upstate NYers.
Penny's Place: one word: breakfast.
Waterloo:
Mac's Drive In: A true roadfood-drive-in-curb-service place. They also sell Hofmann's White and Red Hots. I love the White Hot, also called a Coney by Syracuseans. They're like a brat in a way, but texturally like a hotdog.
Geneva and Canandaigua have lots of good restaurants. Can't think of hotdog stands though or something along those lines. But if you want recs, I'll give some out.
Bloomfield:
Cheap Charlie's: It's not a hotdog place, but their food is great and cheap. Just off 5 & 20 on Maple Ave.
Avon:
Avon Inn: a beautiful greek revival mansion. sounds formal, but it isn't. They call it fine dining, but it's casual dining, and the prices are super cheap. Yes, they do have prime rib and seafood entrees, but they also have lighter fare. They do sunday brunch for under $10. They even have a wing (buffalo wing) night.
5 & 20 split after Avon.
In some ways, NY 5 is better because it goes through some more little towns where US 20 parallels NY 5 but to the south and doesn't go through much until Buffalo.
I feel the same way about 5 around Syracuse Area. Route 20 stays south and there's not much there until Skaneateles, where Route 5 goes through Syracuse, and through towns like Fayetteville and Camillus plus the city. And along that route is a myriad of roadfood joints.
Still, I hope my list through the Finger Lakes helps.
have a safe trip.
