I'm from N.O. and while I do sometimes drink Abita, and compared to many small breweries, they offer some good brews, it's not as good as it could be.
NOLA Brewery has a few good beers and their seasonals are very good.
Martins Wine has some good beers but recently, a few have disappeared and I think they are working with more obscure breweries to get more beer in. Believe it or not, some of the Rouse's grocery stores (local supermarket chain) have a surprisingly good stock of beers you don't normally see in supermarkets.
I love the Avenue pub. Just a homey type feel for me and I get there only about once a month.
Enjoy your stay here, I hope the storms stay out of the gulf. This is not the time of year I would plan a cruise.......8/15-9/15 is the peak of the hurricane season.
