Best Fast Food Chains?

Hey all,

I’m from Michigan… I would say our biggest in the Genesee County area are taco bell, burger king, mcdonalds, tim hortons, ya ya’s and culvers. In your experience - what stores have you been most successful at getting and chaining along 10 to 30 of them - as one big account.

I’m not including subway because they can be independently owned ( probably ost fast food restaurants can be?)
