I've always enjoyed the blue road, especially #23. But most of those shops always seem to be well-stocked and the buildings look nice! PLUS BLUE IS SWAG.
Red because username dominates the prices on that road so the shops past his are always trying to compete with lower prices.
Red is anchored by @_TANSTAAFL at the end. After KMax and usernameofdeath, the shops on the red road are not as good as the other colors, just my opinion (I'm sorry!).
I meant his does the most business, does it not? Yours is quite good too, and it is nice that you are right across from his.
It's really about customer loyalty. For example, I travel to only a few shops because I know they will either have a lot of funds, or a great prices.
I mostly buy from @usernameofdeath @Iticip @KMaxwell (some cheap food you got there) and @_TANSTAAFL , it's red for me I guess.
