If you are willing to venture out of the city, South Louisiana has a fantastic brewery that is open for the public to visit.  The Abita Brewery is across lake Ponchatrain in Abita Springs, LA.  This is just a guesstimate, but it would probably take you an hour to get there by car.  If you the have time and inclination to make the trip, it would be worth your while.  Just be sure to check their times.  They are somewhat limited on Weekdays.  However, if not, you can find Abita Beer just about anywhere in New Orleans where beer is served.  Make sure to give their signature Purple Haze a try.
