Drugstores and Babystores are neutral or negative to food and shops. Boutiques, Salons, Jewelries go well. Bookstores fit to no food (neutral), but to Tattoo Shops, Gadgets, Music and Toys. Supermarkets are neutral to Shops, but go well with Food. Gadgets go well with Entertainment. Cinema fits to most food. Restrooms complete Cafe, Liquor, Arcade and Cinema, but are neutral or negative to the others. Put Restrooms on each floor: Customers will rather walk to the other end of the floor than using one escalator. I built three on each floor, two at the far end and one in the middle, always next to an elevator. Build Elevators on each end, that way the entire map has a ceiling and you can build on second stories and skipping the first one; you will want to do keep the Halls on the floor. I have not unlocked the final shop and food yet and skipped the more particular compatibilities, so this list is incomplete :3
