If you like great service and fantastic food:
Fogo De Chao
Chima
These are both different Brazilian steakhouses. Chima is located at 19th & JFK (a little further out) and Fogo is around the 11th/12th street area and Locust (I think).
If you sign up on Chimas website you get either a 1/2 off or $25 coupon. Fogo also has lunch at a reasonable price whereas Chima does not serve lunch. The food is amazing.. and the service is wonderful.
A former work colleague loves Le Bec Fin. They are closing soon-- so if you want to try it, go soon.
Budakan is a great choice. I used to walk past it almost every day.. it always smelled delicious.
There is also a new casino not far from that area called SugarHouse. You would either take a cab.. you can't really walk it from the subway station.. (I tried to do it and it was pretty dangerous)
I can't remember the cross streets of the Loew's. The Market Frankford El (The Subway) is actually really good in the downtown area. There are stops at 2nd, 5th, 8th, 11th, 13th, 15th. I never had a problem on the El-- used to take it daily! A3ll of those stops would be tourist stops. Spring Garden (after 2nd) is not a touristy area, and neither is 30.th
