Cusser's Roast Beef and Seafood in Boston

So yes, I was trying to save my stomach for a roast beef sandwich this afternoon, and this shop had a stall inside the big Time Out Market food hall at Landmark Center (401 Park Drive). The beef was actually wagyu, but it was too difficult to taste given that it was covered up by the cheese, sauce, and pickled onions. Eventually, I just put all the other stuff aside so that I could get straight to the beef.
