When 'Gotham' came back from its holiday break, the show came so close to making a theoretical connection to 'The Sopranos'. And even the fact that they are in two separate Toobworlds - Earth Prime-Time for 'The Sopranos' and Comic Book Toobworld for 'Gotham'.
(Earth Prime-Time already had its own Gotham City, quite a visitors' destination back in the mid-1960s.)
But when Butch and another mobster were reminiscing about their childhood together, Butch mentioned the time they hit the Satriani meat market for a truckload of meat. If only it had been Satriale's Pork Store... then I could have linked 'Gotham' to the meeting place for Tony Soprano and his crew. Just because 'The Sopranos' took place in the main Toobworld, that doesn't mean they didn't have doppelgangers in Comic Book Toobworld.
