For dinner you could do Jean-Georges Philadelphia. They do have a dress code although not as strict as jacket required. On the cocktail side of things you could try Hop Sing Laundromat. The owner has both a dress code and behavior rules so you won’t be in there with people in sportswear. Unfortunately, I can’t help you on the night club side of things.
Back in the day Le Bec-Fin would have been the restaurant for you. Required jackets, the servers wore tuxedos, and the place was pretty opulent. They closed after things got more casual and that type of dining went out of style.
