I've never been to Nawlins, but this place I found on a web search seems worthwhile to check out:
Pickle's Sports & Billiards
1012 Jefferson Hwy
New Orleans, LA 70121
504-828-0048 Pickle's Sports & Billiards - After work ends, working-class folk stop by Pickle's for a few tall beers and an equal number of pool games. The unpretentious pool hall offers it patrons of all ages nine pool tables, a big-screen TV, darts and video poker. Serious pool players congregate after dinnertime, so be on the lookout for anyone who might want to hustle ya'.
