The Judge's Tent behind Mickey's House and Town Square/ Main Entrance area at MK, the Character Connection in Innoventions at EPCOT (it's on the left in the breezeway between Innoventions Plaza and where The Land, Living Seas, and Imagination are) and sometimes at the Sorcerer's Hat at Disney-MGM Studios. Out of those, usually the Character Connection and the Judge's Tent tend to have the shortest lines. Plus, both locations are inside and air conditioned! I'm pretty sure that none of the character meals feature him in that outfit.
