You can see that same party store in some exterior shots of the Bing. Puss really taking a risk going across the parking lot to talk to his handler. Though I don't think they're meant to be the same place. Stupid idea to have Jimmy be an Elvis impersonator, they could have found a more realistic and innocent way for him to be spotted by a made guy. Probably one of those things they'd like a do over on in retrospect.
