Toying with the idea of of spending a couple of days in the city and trying the "best of" carts, stools, small take out and maybe "no sitting places" etc, which i will "complete" along the way with the best of chocolate/ice cream/bakeries etc. Is SF a good place to do so, and i can find good places for ethnic food, informal but very fresh seafood, dim sum, local specialities and whatever other places you may like under this "street category" ? What are your goto places for this? Going slowly through the archive, will appriciate any help, maybe such tours are a good idea..
