The only 2 days I spent in Philadelphia were for summer law firm interviews, and I was determined to solve the mystery in my own mind. They put me in some luxury hotel so I had to ride on the subway quite a bit, but I eventually found Pat's and Geno's after drunkenly stumbling around for a while. I had Pat's the first night, and the second day (after the interview, mind you) I had Geno's. Gotta say I preferred my Geno's whiz wit. I would never in a million years considered getting whiz, but luckily my favorite professor was from Philly and he threatened my life if I didn't get whiz. I took his advice, and I was satisfied. Geno's whiz wit.
