BBQ in downtown Philadelphia?

Can anyone direct me to a decent Q joint in the downtown area of Philadelphia? I will be at the Convention Center without transportation, so any decent BBQ establishments within walking distance is what I'm looking for.

Your comments and information will be greatly appreciated!

Near the Convention Center, I would recommend the Smoked Joint, which is at 14th and Locust. Definitely walkable from the Convention Center area.
