Re:Frozen Custard in Philly: Shake Shack now open!
I was very impressed by my burger and black & white malt last week.
Just a little while ago, I went back for a quick frozen custard while I was in the neighborhood. They've got a few unique-to-Philadelphia concretes. I ordered one with vanilla custard, pureed strawberries, broken up cannoli pieces and sweet lemon ricotta. It was unbelievably good, although I can't really judge the quality of the custard until I have it plain.
They have a separate line for people who are only ordering custard or beverages and there was almost no wait at all. The burger line was back to around the door both times I was there, but that's not really that long, especially in comparison to the lines in the park and at Citi Field in New York.
