Man, I'm going to be perfectly honest here. Yes, there are varying qualities of smoked meat. No, you probably won't know the fucking difference. Even the assholes who swear by schwartz's or place X or what have you would probably fucking fail the pepsi challenge in this regard.

Smoked meat is pretty much good everywhere, so long as you have some guarantee that it is fresh and well-prepared.

With that in mind, pretty much any deli or any restaurant advertising smoked meat is probably a decent gamble.
