The Mill Valley location runs on a straightforward lineup built around never-frozen beef patties, crisp hand-leafed lettuce, fresh tomatoes, signature secret spread, and thick shakes. An efficient drive-thru keeps the queue moving, while those looking beyond the compact posted board can call for off-menu staples like Animal Style burgers and fries.
