Two things: a) it's Din Tai Fung; and b) nobody who's aiming for The Cheesecake Factory across the street from the convention center is going to accidentally wind up at the Pacific Place (or, worse, UVillage) Din Tai Fung.
They are completely different menus and dining experiences. Though if The Cheesecake Factory ever adds soup dumplings to their menu, I bet they will be pretty good and cheaper.
