(UPDATE: Seems they given this up and the owner is strictly concentrating on his catering and brick and mortar location called Market & Rye.)
Me and the SO are cruising down Valencia Street and pass by McCoppin Street plaza where Off the Grid has a Saturday food truck thing that goes on. I say "hey, I'm hungry let's stop." So we pull over and the parking goddess is on our side as we get a spot right on the corner. This day there are 5 trucks and after perusing each menu, which I like to do and the SO likes to roll his eyes at me, we decided to give the 3 Sum Eats truck a go.
