is pat's and geno's considered South philly in general or more specifically italian market as a neighborhood. The reason i asked is that someone recently told me it was "wharton" and i never heard of that term for the area.

I've heard it called Wharton. Names are just names, don't worry about it too much. I've seen ads for stuff around 11th & Jackson advertised as "Italian Market area." Pat's and Geno's are very close to the Italian Market, but usually people think of the IM as being part of "Bella Vista," which is wholly north of Washington Ave. Pat's and Geno's would be part of "Passyunk Square."
