This little "Thai" place on 18th near Mission used to be called Yamo Thai Kitchen, but a Taiwanese man took it over about a month ago and changed lots of things, including the name, which now pays homage to the Doobie Brothers song.
The menu is really tiny -- there were a couple of soups, about 3 rice dishes, 3 noodle dishes, and a few other things. (No liquor license yet, so you can buy beer around the corner and bring it). The soups were around $6 and huge, easily enough for 2 people. Different from your normal Thai soup -- with big pieces of fried tofu and a very porous vegetable I don't know (I think he called it a water chestnut, but it was greenish and softer). Spring rolls are raw, very thick, and come with a peanut sauce that was brewing over the stove. Not very strong tastes, but light, interesting, cheap, and original.
Most of the seating is at the long bar. The best feature may be the placemats, which according to the owner are stills from a late 1960s Thai movie (think Hawaii 5-0 in Bangkok). He said he just got the movie itself and will be projecting it on a wall in the future.
