Hello fellow Philly Packer fan! I hunted around and found some places. I've never been to any of them so I hope they are OK! Be safe if you head out in Packers gear, as I'm sure you know, Eagles fans can be vicious. I'd think their blood is really set on boil after the Packers knocked them out of the playoffs. So just take care of you!
I don't think any of these are specific Packer bars, just known to be a bit less hostile.

Also, but don't quote me on this, I think the owner of Dagwoods Pub is a Cheesehead. If it is the same place I saw on the news on the day of they Eagles/ Packers game, they were broadcasting from there and the owner was wearing a Cheesehead hat. They might be a bit pricier if you want food but I heard the food is good. I hope this helps you out! It's great to meet another Philly Packers fan!
