How Awesome is this????

Yesterday, JERRY SEINFELD and JASON ALEXANDER were spotted at Tom's Restaurant in NYC.... (Monk's Café) . . . their old hangout from "Seinfeld".

 

Rumor is.... that they were there to film a Super Bowl commercial.  Tom's was closed at the time . . . a camera crew was there . . . and so was "Seinfeld" co-creator LARRY DAVID.

They also could have been filming something for Jerry's online series, "Comedians in Cars Getting Coffee".

 TMZ has video of Jerry telling the paparazzi that the whole thing is "top secret.
