Ditto on that Monsoon. My dear lord that is a drink. But if you start with Monsoons at Port of Call, you might not make it much farther!
Staying in the Quarter (because traipsing over to the 9th ward or Garden District will be more challenging without proper transportation and New Orleans is best on foot, I say...
Start with one of those overpriced Hurricanes at the Daiquiri Stand of your choice (I like Mango Mango because it is fun to say), you'll need it in the humidity.
Hit the Gumbo Shop for a cup of decent gumbo, but you MUST get the boudin appetizer.
Nearby you can grab your main meal at the Old Coffee Pot, here you can get a REAL Hurricane and pretty much anything else you want. The crawfish etouffee is pretty solid, the only thing I would pass on is the corn maque choux, it is a little bland. The steaks are great as well.
Obviously for dessert, you'll be going for biegnets and chicory at Cafe Du Monde (you just really have to go), but there are also some really nice praline shops along Decatur near the French Market. (maybe tomorrow...)
Pat O's will be rolling by this time, so head over there for some MORE Hurricanes and sing-a-long fun.
But, wait the night is not yet over, not until you've kicked back a few brews and had some late night rabbit jambalaya and shrimp creole at Coop's Place (also on Decatur).
The next day, you'll want to work all of this off with a trip to Central Grocery for the Muffaletta. (and you'll please please bring me one back??
)
Enjoy your trip. I so miss New Orleans, much like the song says...sigh....
