I have been looking for 4 years. Let me know if you find anything.
Been here for 7 years. You won't find it because sports bars dedicated to any other team (than the Eagles) is likely to get fire-bombed. I'm sure you're well aware of the inferiority complex people in this city have with New York (and any other city for that matter) It's sad.
i went to college in Philly (Drexel University) until 2001... I used to go to Cavanaughs in University City (basically on UPenn's campus) - i believe like 39th and Chestnut... not really a "Jets bar" but they used to get a ton of Jets fans there who were college students at either Drexel or Penn...
Since I graduated - they have opened up a ton of newer sports bars in University City so I am not sure Cav's is still the spot but I would suggest going to that area if you want to be around other Jets fans as being on a college campus is your best chance of being around other New Yorkers in Philly..
