The service is perfect, the food simply the best. I first ate here in 1969. It was the best Sub then, and the # 7 with everything is still the best sandwich of ANY kind I have ever eaten. When I am in the L.A. area, I make a point of going out of my way to visit My Hero. There is NOTHING else as good in the field. I say this having built and operated three sandwich shops over the last 35 years, and while mine are good too, My Hero set the standard.
Pros: Best food of it's type anywhere.
Cons: There is not one in northern california.
