I wished they had created more space for the Milk Bar within the Momofuku's 3 floors. It is kind of in an awkward space, and after you get all your goodies there is no place to sit so they turn you out. You have to go up stairs, grab your stuff and then awkwardly wait while the crazy busy waiters are running around, and you have to wait for them to check you out.
Other than the soft-serve, I wouldn't recommend getting anything else. The cookies and cakes all sound good, but they don't taste that good and are pretty overpriced. I would stick with their cereal milk ice cream because it's always good and the novelty never wears off.
