From what I can see Chicago, is the only other city in the US with 2. LA County has 4. And the New Jersey/New York locations are about as far as the Philly locations.

Globally I found Toronto, Montreal, Vancouver, Barcelona, and Manchester have 2 Brussels, and Amsterdam have 3 Madrid and London have 4, and Paris has 7. (Looking at metro areas)

There's more areas that have multiple, and neighboring area with ones too, especially as you go Eastern Europe and the Nordic regions. Stockholm has 2. Älmhult has the one, but it's filled with all the corporate buildings, museum, and hotel
