I love Al's on State Street (near Broad). Classic subs, hot and cold; still-warm rolls, always fresh food, always ripe and tasty tomatoes. High volume at lunch, tiny and crammed with 15 or 18 yellow-shirted workerbees and many take-out patrons (there are a few stools). And all subs are $4. and $6. Open Saturdays. Next door is Sultan's Kitchen. Superior middle-eastern food, sandwiches, entrees and desserts. Would love to hear of other favorites, as I am moving my office to that part of Boston soon.
