Has always (since i was 18) been a pit stop when visiting MTL either coming from or going to Karmasutra. Best smoked meat i've ever had bar (rafaeli) none. Here's why:
Katz's - too dry and has this sulphuric chemical taste
Carnegie - tasteless not smokey and not enough fat
Queens/Kings Deli - on par but doesn't have the personal nostalgia of this long standing establishment.
Reason it's not a five is the long wait, the travel time to MTL, and s***tty attitude of the waiters - ahh their just characters. Park at the lot behind Moishe's. slaw, pickles,and the "fat cut" are a must.
