The Mexican restaurant in the SFO UA International Terminal, not good at all. However there is a great sandwich/deli outlet in the same terminal, they have prepared sandwiches which are nice but will prepare a fresh made one for you, all kinds of bread, cheeses meats etc. Also very good salads and other choice goodies. Always take one of their sandwiches on the plane. In fact an FA coming by serving dinner wanted to know where the sandwich was from it looked so good to her.
