I'm not sure if this is a big deal in other places, but the trend in Ess Eff these days is to serve high-end street food out of repurposed Mexican-food trucks.
I guess the idea is to take gourmet food to the people (although the prices are still fairly high, at least compared to buying a hot dog or burrito).
Anyway, the trend has been hugely popular in the Mission district, so a restaurant called Chez Spencer decided to bring the concept to our humble hood. It's not drawing quite the crowds here, but we were definitely excited about being able to buy escargot, frog legs and other French fare without leaving our graffiti-strewn alleyway. (They set up shop in the lot of the oil-change place at the end of Langton Street.)
You can get escargot "popsicles" on sticks for $2 each. Delicious.
I also liked the skate cheeks. The potato-leek soup was a little bland for my tastes, but it did make perfect food for an eight-month-old.
They plan to show up every Thursday through Saturday, so let's hope it works out. There are definitely some detractors, as you can see from these comments (I'm Comment No. 4!).
