Talula’s Garden is a great place too! It is a bit more expensive than the others but is one of my DD favorite restaurants in Philly. For me (not that that matters LOL) I like the brunch choices at Day by Day better.
ETA: On a side note, I just had an unexpected lunch at Day by Day. We went in to pick up something from DD and ended up grabbing lunch while we were there. I guess all the talk about it put it in my mind!
