visited from SF a week or so ago and had some fantastic taiwanese and vietnamese food. keep in mind i was on vacation, so my attention to detail was a little fuzzy:
Rocking Wok- tiny little joint on Interlake in Wallingford (i think). the 'crispy duck' is spectacular. it's got a charred taste and there's not a speck of greasiness, just succulent duck flesh. i'd go back in a nanosecond for this. peddler soup smacked of spice (cinnamon, maybe?) and was the kind of simple, satisfying fare you'd find only at a street vendor's stall. stir-fried rice cakes were great too.
Thanh Vi- Intl Dist. sounds like this one is a familiar institution and for good reason. the bun bo hue was hot in a smooth way, and the cha lua on the banh cuon tasted fresher and less processed than most other versions i've had. nuoc cham was fishier and a bit more viscous (in a good way) than the generic kind in most restaurants. cha gio were wrapped in lumpia wrappers (a big plus for my half-vietnamese cohort who seeks these out like the holy grail) instead of rice paper and were spot-on.
these are the kinds of places i'd frequent time and again if they were located in SF. y'all are lucky.
