ALERT - FOOD TRUCK so you have to check out their Twitter or Facebook page to find out where they are. If anyone has redefined contemporary street food in San Francisco, it’s longtime pals Evan Kidera and Gil Payumo’s Señor Sisig fusion food truck. With their special twist on a Filipino happy hour dish sisig, Señor Sisig took the portability of their favorite Mexican taqueria dishes and melded the two together to reflect their diverse palette and down-home appeal. Though sisig is traditionally made from parts of the pig’s head bought from the butcher to make use of the entire pig, Señor Sisig’s more palatable version uses the meatier pork shoulder.
