Episode: “The Pants Tent” (Season 1, Episode 1)
Despite Larry and Cheryl's best efforts to use Seinfeld as leverage to score a table at this fictional spot (you couldn't tell from the name?), the lack of an available two-top condemns them to an awkward dinner with Jeff, Susie, and Jeff's parents, who LD managed to rub the wrong way with an earlier Hitler comment.
It's the first episode of the show's first season, and the first restaurant featured. Could LD set the tone for the the Curb experience any better than with a Hitler joke? The bar has been set.
