We're moving to Philadelphia next month, and are excited to get to know the city and great dining there! We will be in town this weekend to kick off house-hunting. will be in Rittenhouse Square area on Sunday morning and would like to have a nice meal (brunch, lunch, whatever...) near there. Since it's also mother's day, i feel like I should reserve in advance (or at least know where I am going!) Any suggestions? Not limited on price range.
