Hey sorry I didn't see this yesterday! If you're in New Orleans today as well Mondays may still have a weekly show at the Columns Hotel bar with Michael Doucet and Al Tharpe. Unbelievable! Sip on a sazerac and get your mind blown. Also, Charmaine Neville has a gig today, and Preservation Hall is always a good bet.

Also, I think Cochon Butcher has the best muffalatta in town. They cure their own meats and make their olive salad and hot sauces- that is pretty hard to beat. I don't currently live in New Orleans but I'm definitely a nahlinophile!
Also, I'm working on the cavendish mod as I type.
