Here is another place packed with visual stimuli, along with weird smells and busy sidewalks. I love roaming through all the shops, venturing deep down the aisles to hunting for all things odd and unknown. So much to see, I wish I had extra eyes!
In the Mission, now as terminally hip as it was formally poor, the St Francis is a greasy good time since 1918. Stuck beautifully in the 50's both aesthetically and menu wise it's Americana in a bun. Dig in.
If you can get past the bourgie factor and/or you work down the street like I do, you will come to love this place. It has some of the best food in the city, a Blue Bottle coffee, and an observation deck from which you can watch the ferries come and go, emitting their weird beeps and disgorging tourists. The people who work here are great too (whether or not I dated a baker from the Acme Bread kiosk because of a Craigslist missed connection will be left to history).
This hole-in-the wall noodle shop reminds me a lot of Taipei, an unassuming place that pleasantly surprises the taste buds. San Francisco has endless amounts of amazing food, but this place stands out because of it's size, taste, and prices. There are only about 9 seats in the place but if it's packed, it's worth the wait. While you wait for your noodles or curry, they'll chop open a fresh coconut so you can hydrate yourself before downing a bowl of pure, salty goodness.
