Boy, there are so many places that I love that would cause me pain if they closed. Splitting my time as I do between Philly and NY, I have to pay both locale's their due.
NY:
Benny's Thai, Lower Manhattan
Tokyo Lunch, Lower Manhattan
Cafe El Parador, Midtown
Manganaro's Hero Boy, Midtown
Harold's NY Deli, Edison, NJ
Jackson Diner, Jackson Heights
Many wonderful Chinese and Indian restaurants too numerous to mention
Burger Heaven, SoupBurg, Jackson Hole and numerous other burger joints throughout the city
RIP: Smokey's, Hwa Yuan, Shanghai Manor -- gone but not forgotten
Philly:
Tony Luke's
Lenny's Hot Dogs, Feasterville
Steve's Prince of Steaks
Tortuga's Mexican Village, Princeton, NJ
Turkish Family Restaurant, Bristol
Under the Pier, Bristol
Passage to India, Lawrenceville, NJ
I could go on forever!
And with a nod to Ort. Carlton, two progressive radio stations that I do NOT take for granted - WFUV in NY and WXPN in Philly!
