Breakfast in Bryn Mawr?
There are a few options in Ardmore. Ruby's is probably more what you had in mind, but you can also get breakfast at the Farmers Market (there are tables there) and a chain--Corner Bakery Cafe, I think--just opened across from Ruby's. You're probably already familiar with the Cosi in Bryn Mawr.
Sorry I don't have any great Bryn Mawr recommendations... The Point had breakfast but that is closing this weekend. Tango has Sunday Brunch. The Villanova Diner was horrible... be glad you missed it.
If you're going to drive all the way to Wayne, there are a few great options other than Minella's. Nudy's, about 2 mins further down the road, is my favorite breakfast spot in the area. The menu is very creative and diverse. (review linked below)
Silverspoon Cafe is also pretty good -- right behind South Moon Under before you get to Minella's... they specialize in omelets.
Joe's is right across from blockbuster in Wayne and has the best bacon/egg/cheese or sausage/e/c sandwiches I've had around here.
