My 25 year old son and his wife will be visiting Philadelphia over the Memorial holiday weekend and will be staying at the downtown Hyatt Regency. They are both interested in food although she doesn't eat beef, pork or poultry. Any suggestions for interesting dining or things to do will be appreciated. I imagine they'll do one real nice dinner but they also enjoy finding places the locals like to keep to themselves. They will have a car and plan to see the sights.
Thanks from an Arizona Chowhound.
