Jerry Seinfeld, Larry David, Jason Alexander filming at Tom's Restaurant in New York: 'Shhhhh. It's a secret' Jerry Seinfeld is seen frequenting '90s sitcom haunt Tom's Restaurant with Jason Alexander and a film crew. Seinfeld fans rejoice! Jerry Seinfeld, Jason Alexander, and Larry David have been spotted together at the iconic Tom's Restaurant in New York, as made famous by the classic '90s sitcom Seinfeld. Seinfeld and Alexander, who played George Costanza, were seen walking into the restaurant by Ali Philippides, a keen-eyed pedestrian armed with a smart phone camera which snapped the pair walking down Broadway and into the diner. Philippides posted the image on Twitter. David, co-creator of Seinfeld and brainchild of Curb Your Enthusiasm, was also seen with the pair inside the diner along with a film crew. The restaurant was closed for several hours, with cameras and cables running in and out of the building. The most optimistic Seinfeld fans would be praying for a new episode, or a mini-episode, or anything related to the hugely popular series which aired its final episode in 1998. It's more likely, however, that the trio were filming a superbowl commercial, or perhaps something more? The only clue was Alexander's tweet: "Hey everybody, you'll never guess what I did today. Shhhhh. It's a secret. The latest spotting comes off the back of Seinfeld and David's recent Reddit AMA (Ask Me Anything) session in which the pair hinted at a joint project that was "big, huge, gigantic." "We never obsess over anything that isn't mundane," Seinfeld stated. Most recent was intentional mumbling. We wrote this script for this thing that you will eventually see but I can't reveal what it is at this time. All I can do is tell you is that it's big, huge, gigantic. Even bigger than that Amazon package. Yet it has since been reported that David has in fact written a play. The Curb Your Enthusiasm star told Showbiz 411 that he was still "talking about it" with Seinfeld.
