Jim’s is on South at about 4th. My preference is part nostalgia and that I think they chop the meat finer. Delicious.
I’m not familiar with Jim’s myself, but I texted my son who ate his way through 4 years in college in Philly.
(texting is the only way to get a sure response from anyone in that generation.)
He texts back “good but not as good as pats”.
