Does uptown ever get food carts or the grocery stand?

Thanks for the response @Kita5399! I will keep watching for them now because of what you said. I thought I was thorough in where I looked, but I'll also make sure i'm looking at the upper level.
I felt that I saw a vendor up there in the past at least one of the times when visiting the Gym in that neighborhood, so your reply just confirms I'm not remembering wrong. Eliza Pancakes was the vendor...that's why I remember it.
