In "The Jacket", the gang supposedly ate at a Pakistani Restaurant with Alton Benes after leaving the hotel lobby (Jerry's new suede jacket getting ruined en route).
However, 16 episodes later in "The Cafe", Jerry gives Babu Bhatt the idea to change his restaurant into all-Pakistani, because there aren't any in NYC (IIRC).
Either Jerry is not remembering this prior visit to a Pakistani restaurant, or the restaurant closed soon thereafter and he intentionally gave Babu bad advice (where are people?... I do not see people!... show me people!). Perhaps not an inconsistency per se, but at least it connects two of the episodes.
Also a Seinfeld mystery: Just how much did that suede jacket cost? At least over $1000, right?
