My mom and grandma are coming down from NJ so I can take them out to Mother's Day brunch (which happens to be right smack in the middle of finals period, hence my urgent cry for help). My brother is meeting us in Philly, and he'll be taking the train, so I guess something around center-city (the UPenn area?) would be good. Nothing exorbitantly expensive, but I'm willing to spend around $20 per person. It doesn't even have to be a brunch, even a nice lunch would be great. And the grandma's a little picky =), so nothing too exotic. All suggestions GREATLY APPRECIATED. Thanks a bunch!
