Seeing a line outside a restaurant year round is usually a good sign, and in this case, it certainly is!
A mound of lean, regular or fatty (artery clogging) served on seemingly tiny slices of bread with mustard, this smoked meat sandwich is to die for! I would eat here regularly if it wouldn't plug my arteries. The balance of flavors for the meat, mustard, and rye bread is great and will certainly fill you up!
The wait can be daunting sometimes, but it's certainly worth giving it a try!
