I am not really a burrito person either, but the 1 mile house is SLAAAPPPPPPP! Ask premo, he know!
The one on Mare Island leaves at 4 because it is pretty much there to feed lunch to the people who wok over there and don't have much of a choice. They have this thing that is kinda like a Tostada, called a Hurraches or some shit, and its a thick freshly fried corn tortilla with hella shit piled on it for $6. Hella good and hella filling. I fucks with their Torta Cubana, too.
That reminds me, for $7 you can get a super torta from the 1mile house spot, and it will fill ou up for 2 days. and that is the only place in town that I have found carne asada fries.
