Not really. Granted, most pokémon have certain foods their entire species can’t eat (a big one is chocolate for many mammalian pokémon), but most trainers will already know this. It’s just important to have a portion of your menu dedicated to healthier (lower fats or sugars) and vegetarian options, as these are often safe for all pokémon (as well as humans, of course).
Hey bill, Restaurant owner here again. I wanna say thanks for the suggestion. I’m already having my cooks work on reduced Sugar menu items, though i did have to knock some sense into one of my busboys who put Tamato sauce on a table instead of Tomato ketchup in hopes of dissuading further experiences like that pikachu that guzzled that whole ketchup bottle. By the way, are there any other pokemon with specialized dietary needs that might be a problem on my budget?
