Like others, I didn't want to go for the obvious choice of a park. I also wanted to see if I could build the structure over the river and thought I would do a restaurant. Lots of fiddling with tables later, I decided to go for the clothes shop, since that fitted better on my tiny structure.
I actually didn't remember the business description properly and thought it was something along the lines of 'a clothes shop for everyone in your village'. So I thought that I should use all that empty space and put something down that would entertain the kids and adults that aren't very interested in shopping.
There's a playground for the kids, safely fenced in so they don't drown in the river.....
.....and a playground for the bored adults too!
I have playtested the shop, shopping goes fine, as does paying at the register, haven't seen any routing issues so far. Other than the congregating in the bathroom which they seem to do everywhere!
