It would be safe to eat because the food comes out plain, with no seasoning. You make your own bowl of spices & seasonings, so there shouldn't be any surprises.
Im sure there are things you can eat, but quality of ingredients used there isnt worth the price.
Chili pepper? I believe there is more than one soup stocks not contain pepper. Just don't choose sauces that contain pepper, and enjoy!
