Hello, fellow Chowhounds! I am trying to arrange a business dinner for 6-8 in Phildelphia next month. I'm in Washington, DC, so am unfamiliar with restaurants in Phildelphia and would greatly appreciate any recommendations you can throw my way. The restaurant needs to be on the upscale side, good food and very good wine. Looking more for American, French or Italian fare or a good steakhouse. Any input is welcome and thank you for your help!
