In one sense, Le Truc is one of the most stable food “trucks” in San Francisco. The owners pay rent to Wells Fargo bank to park what's actually a converted schoolbus in its lot at 470 Brannan (at Fourth St.) all day every weekday.

Perhaps it's natural, then, that Le Truc should have a chef change, just like completely stable restaurants. Many food trucks simply cease to exist when a founder leaves. But when original partner Hugh Schick walked away, the remaining partners brought in Jessie Rivas, a former executive chef from Potrero Brewing Company.

Rivas and new sous-chef Tevye Nieto have put more salads on the menu. But the emphasis remains meat sandwiches, particularly burgers.

And a special feature remains that because Le Truc is actually a bus (is that a bad French thing?), you can sit inside on comfy benches and watch the crew make your lunch.
