Taste of Heaven is a good alternative to Pasticceria Natalina if you want to sit down; it's right across the street. They have fantastic cakes, especially their carrot cake and another whose name I can't recall, but it's basically yellow cake with whipped cream frosting and three kinds of berries in the middle layer.
But neither is very close to Katsu, especially if coming back from Katsu you'd be passing Lincoln Square-which-is-home.
I don't have a lot of better suggestions for proximity, but that Chocolate Shoppe location is much much closer.
