Welcome to the City! I have lived hear most of my adult life and find it one of the best places to live.
As for money, there is a wage tax that is under 4%, the sales tax is 1% higher than the burbs and your car insurance may go up (but you should sell the car and use www.phillycarshare.com ).
If you are self employed, there is a gross and net profits tax instead of the wage tax. I suggest contacting your accountant would be the best idea.
If you need restaurant suggestions, let me know.
