Looking for some help from some fellow Chowhounders out there. I am planning a client dinner in Philly next week and this will be the client's first visit to Philadelphia. My usual go to is Osteria, but I thought I might ask for some suggestions as to any restaurants that might be "Quintessentially Philly." I'm looking for something a bit higher end that really gives you the feeling that you are in Philly. I was thinking Water Works, but it has been hit or miss in my experience. Any thoughts on Nineteen? All suggestions are welcome.
