I tried a bakery once but I couldn't make it work like I envisioned (a faster more informal restaurant), so it now exclusively sells wedding cakes and posh pastries for events, no tasting on site.
My sims still run it and they have the Fresh Chef reward trait so its real usefulness is when another playable family has a party to plan: no more forgetting about the wedding cake, they just pop by to buy it beforehand and it doesn't spoil.
As for my bakery wish, a mod adding more food to espresso bars makes-do for my gameplay, even if I don't run the cafés. (I really hope Seasons hot chocolate is added to the espresso bar though).
Still salty that Dine Out didn't have less formal restaurant gameplay for burger joints, pizzerias, ice cream shops ...
Food stands scratch the itch, but only barely.
Good luck for your first retail ! I'm sure if you're not as obsessed with efficiency as I am, you'll only have tons of fun.
