Check out the Dorayaki at the Ranch Market, if you get there on time, they make a red bean paste pancake on a griddle in front of the store. Deelish! Go to the Szechwan Palace and request the non-English menu for the true authentic items. The gift shop has tons of gift ideas if you are stumped. I might also mention they have some really, really nice shrines made out of cherry wood and lacquer. I was in the market for one to make my altar and these are the real deal. Beautiful furniture finds, although they can be a bit pricey. They are willing to negotiate with you if you ask.
The store has what you need but the variety may seem lacking in comparison to Lee Lee's or Mekong. Anything you try at the bakery is amazing, if you are in the mood for perfect deco-den like whipped cream cakes, this is the place to get it. Their fruit selection is lacking which is probably my only gripe, but they make up for it in their vegetable selection. The Chinese Herb shop next door is a great place if you are into holistic/Chinese medicine. I wish this place was bigger with more stores, that would definitely put it over the top.
