Mendocino Farms in Marina Del Rey has some great ones. One of my favorites is their Prosciutto & Roasted Chicken with local Gioia fresh mozzarella, crushed honey roasted almonds, basil pesto, balsamic vinegar, tomatoes on panini grilled ciabatta. Good sandwich.

Along these same lines, does anyone have an opinion on the restaurant Il Tramezzino? It's supposedly known for its paninis. They have locations in BH and in the Valley. I'm curious because they are opening up on the UCLA campus in the old Espresso Roma location.
