I just moved to the city in December from Kansas, but largely due to very little money have ended up at the extreme south end of San Francisco (yes, technically, we're still across the line...) near the Daly City BART station. This means that trips into the city for food are surprisingly problematic. Either we drive and spend forever trying to find a place to park or we take the bus and spend at least an hour and a half plus transfers just to get there. While we plan to move ASAP for the moment we're trying to find decent places to eat that are at least reasonably close by.
Since we live here I'm more concerned with finding new staples to add to our standard dining out rotation than spending forever just to try out the best place in city. Likewise we're still poor with only one entry-level job between two post-grads and want to keep things on a bit of a budget (i.e. under $20 for two teetotalers, although coming from Kansas City we're still trying to get a good fix on what constitutes a reasonable price).
From my excursions around the neighborhood (such as it is) there doesn't really seem to be anything out here. Just a bunch of run-down houses and a strip mall or two, but for the meantime while we're stuck out in this end of town we'd like to try getting a bit of a clue about what might be worth our while.
