"Beef on weck is a whole Buffalo vibe, so it may seem like a strange decision to put a version of it on a map of Boston’s most essential sandwiches. But All Star Sandwich Bar’s take on it — one of the only beef on wecks to be found in the Boston area — is too good not to make the list. Warm, thinly sliced-to-order roast beef is piled high on a kimmelweck roll, topped with spicy horseradish and au jus. It’s outstanding." - Erika Adams, Nathan Tavares
