As far as restaurants go I'm not sure. I have one restaurant-like building planned called La Michoacana. It's a famous ice cream chain in Mexico that sells hand-made popsicles, ice cream, and treats. It turns out they lost the rights to their trademark in the US so it's why, if you're American anyway, you might see them everywhere in the US. They're not a chain here, but everyone has taken advantage of the trademark ruling to call their ice cream store the same name because it sells. And so will I for this mod lmao.
Anyway, I just don't know where to go creatively with a big building that sells food because the one in the game already kind of matches this pueblo style, so it's already been done and I kind of want to avoid making a similar one. After the last two stands I'm going to take a small break on the foods and experiment with fences, fountains, and other misc objects. I want this to be a full theme pack.
Edit: maybe I can add in a 'hack' that adds some of these food items to the restaurant already in the game.
