Thanks to ms.sunshine for the tip on Dean Sin World in Monterey Park. I never would have found it since, as the original thread indicated, the outside English signage still says "Tastio Bakery," though I imagine that the Chinese language banner on the awning probably says something about dumplings. Basically they took the old bakery space and divided it in half--one half for four tables and a dozen chairs, the other half for a work area where you can watch a lady make noodles and dumplings. Certainly the antithesis of Din Tai Fung with its bustle and teams of chefs and preparers in action, as the lady noodlemaker at Dean Sin World also takes orders and probably helps out in serving, too, since she's performing only part of the time. Not being a connoisseur of XLB, I'm not qualified to rate the product here, except to say that the XLB had the sweetest broth ("hem" in Toishanese) I've encountered and was extra juicy. Dean Sin World is at 306 N. Garfield, #2, directly across the street from Qingdao Bread Food (the place with the great fish dumplings) and in front of Giang Nan.
