Here are some of my favorites (more like HK style food)
Golden Gate Bakery in SF Chinatown for the daan taat, but call before going. I walked by last night and the owners decided to shutter for 2 weeks vacation. Not sure when this 2 weeks starts or ends. It’s even more expensive that Tai Cheong (though cookie crust, unlike GG’s puff pastry that’s not as puffy as before) in Hong Kong…$1.75 a piece here, but very very tasty.
Tak Kee Lee (Noriega) in the Sunset - hit them up for breakfast. You can customize your noodle bowl with upwards of 3 items. Satay beef, pork chop, pickled mustard greens pork strips, zacai pork strip, sunny fried egg, spam, with either rice noodles (mai fun) or instant noodles are very solid, hit the spot and fantastic value. If the older guy with glasses is at the cashier (he makes the drinks), the HK style lemon tea is the best in town. Otherwise HK milk tea very good and ditto for their milk tea coffee. If you miss the breakfast, their lemongrass fried chicken wing rice plate is ridiculously good. Mostly Cantonese expat locals. If you like Cantonese shui gow, Ming Tai a few doors down is not bad for that.
Yum’s Bistro (Fremont) - it’s further away from SF but it’s the best in town for anything from seafood to stir fry.
Marco Polo Gelato (Taraval street) - this is so uniquely fun and SF. If you love durian, their durian gelato is ridiculously good. If not, try their Chinese dragonwell green tea flavor, black sesame (my favorite). They also have jackfruit, lychee, guava, taro, red bean. Up the street from there is Smile House Cafe which is probably the best HK cafe that focuses on fun funky fusion. Don’t expect good service there. The HK style Hainan Chicken Rice is decent, and their tom yum baked spaghetti is great. If you like ox tongue, try the ox tongue spaghetti in spicy tomato sauce, quite fun. And their signature cold milk tea in a bottle resting in a bucket of ice is nicely done. No iced coffee here though.
Dragon Beaux in SF (on Geary Blvd) for dim sum. Go early (a bit before they open).
If you must do Koi Palace, Dublin and Milpitas locations are better bets, though a lot further away.
Ming Kee on Ocean is an interesting neighborhood roasties deli. If you have quota to spare, do a roasties combo rice plate but more importantly go for the soy sauce chicken (the non range chicken will be plumper and meatier). Cha siu is ok but they slice it thin. Ming is one of very few roasties butchers who is actually a HK expat (and not Toishanese form China). On the way there you will pass by Zanze’s cheesecake, if somehow they are open and have inventory, their cheesecakes are so damn good, and oftentimes even lighter than many Japanese style cheesecakes (you have to cut it with a floss line…) Pick up a small and try it.
