That's a Babies R Us now.
I work right off of Causeway, so I spend an inordinate amount of time in that entire part of Metairie. However, I've mastered going to Gamestop.
Go over Vets to 17th and enter lakeside via the back. If you're picking up a reserve game, park in the loading zone by the back entrance on the Causeway side (where the yogurt stand is). Put your hazards on and just run in.
If you need more time, park either in the garage by Dillards or on the side across from Phil's and cut through JCPenny's.
I can do either and be back in the office in about 15 minutes.
