Stumbled across this new gem of a place in the Castro which serves quality sausages served with condiments made onsite. Loved the Hawaiian Portuguese sausage served with grilled onions and curry catsup! Very reasonable.... $4.50 (including tax) for a sandwich with two dressings and two condiments.
Good to know that there's something tasty, quick and inexpensive that's available until midnight everyday!
They're on the corner of Market and 14th.... in the old Cafe Cuvee space.
