Ate here twice while spending a few days in Philly.
The food is really good. A lovely casual dining spot. Good wines, and a cider on tap. No GF beer.
The menu is digital, but if you ask they'll give you a laminated version. Handy if you don't have internet. They don't have in-house wifi.
Any item that cannot be made gf, or isn't already gf, is marked. Loads of choice.
