I like Asian cuisine of all types - Japanese, Chinese, Vietnamese, Korean, Thai, you name it.
Neither of these is cuisine.
Of the two, the Lotus Blossom is the one I would pick. I do really like the noodle soup, and there are a couple of other things on their menu that are pretty good. The proximity of the plum-wine slushies is a plus too.
Yakitori House is a no-go. If it was the only place open in the whole park, I would walk to the vending machines out by the bus zone.
