Frankie from Pat's Cheesesteak developed quite a few new sodas available at Pat's Cheesesteak. I was there last weekend, and absolutely loved their vanilla cream soda. Just like the old Frank's used to be.
I wish the hot chili pepper flakes is still available (instead of the whole big dry chili in the tub). The ketchup dispenser that were replaced last summer is cool and convenient. of course that was well talked about at the FS mailing list a while ago.
