I would definitely go for your friend's dish, it looks amazing and the combination of flavors is very tasty, which you describe so well, it sounds spectacular. Too bad you are allergic, in your situation I would not have dared to try it.
You are right in describing that menu as a book hahaha it is very complete, but I think it is a good idea when the food you prepare is something exotic like that. If I hadn't read the explanation you followed to eat ramen the right way, I wouldn't have had any idea about it. I'm writing it down for when I have the chance to try it, because indeed, I've never eaten ramen, shame on me hahaha.
