It's a trek, but I love Hosmer Mountain Soda in Willimantic, CT. https://hosmersoda.com/

Very old family owned soda company that sterilizes and reuses their glass bottles and has a lot of fun old school flavors. I know some grocery stores have them so maybe they are available somewhere closer but you might have to call and ask.

I think people like the pizza and hot dogs partially just because they're so cheap, not because they're the best around.
