I've been to a few Lee's Sandwiches in CA. This one is pretty much the same, although slightly more organized on the inside than the few I've been to.
Their special sandwich is almost as good as some of the top banh mi places I've been to in CA and MN. Service was fast and their menus are nice and big. Their pick up area is well marked and hard to miss and they have ample seats for people who want to dine in.
They skimp on the toppings, big time. You have to order extra meat with every sandwich because they will literally put one slice of meat in. They charge you too much for extra meat as well, in an absurd way too. Let me explain, if you purchase a sandwich that has 3 different kinds of meat in it, they charge you almost $1 extra for each kind of meat you want extra, so a $3 sandwich that's light on toppings would turn into a $6 sandwich. Their Vietnamese offerings (ie egg rolls, other fried goodies) had clearly been sitting too long under their warming lights.
They are the only place to get banh mi within the Phoenix metro area that isn't terrible. The value is not good, and you WILL have to load up on extra meat do to topping sparseness. Supply and demand, they have it, no one else does, and they charge an arm and a leg for it.
