Congrats on three years, that is awesome! Yall will have a blast in New Orleans. Where will yall be staying?
Recs:
Katie's in mid-city is my current favorite "hole in the wall" type restaurant. Very reasonable prices, unbelievable seafood. My favorite is the Catfish Meuniere, which is fried catfish served over fries smothered in the most insane meuniere gravy. $16.
Johnny's Po-Boys in the quarter. Line will always be out the door, check the hours I think its lunch only. Basically its like 50 million different kinds of poboys, all delicious. Cash only. Get a poboy and walk down royal street eating it, looking at all the fancy art.
Cafe Du Monde. Yeah yeah its touristy but its fucking good. I go to New Orleans a lot, and I always manage to find my way there. Its 24 hours, they only serve coffee and beignets. Get a cafe au lait and a couple orders of beignets and go nuts on them. Open 24 hours, hell yeah.
Daisy Dukes - right off the side of the Marriott on canal, a true hole in the wall, open 24 hours, DOPE ASS food. My favorite late night eating spot in the quarter. Get a po boy, gumbo, and pancakes, you'll go to carb heaven.
And if you DO decide to splurge, since after all you are in one of the greatest food cities in the world, its hard to go wrong with Commanders Palace. You'll need a reservation and a coat and tie, but the service is top notch, and the food amazing. I had the pecan candied quail last time I went. Makes me tear up a little just thinking about it.
Music wise, looking at the music calendar on wwoz:
Aug 8th - Raw Oyster Cult at Tips Uptown. Tipitinas is a classic venue but when its packed its pretty miserable. Might not be your thing but Raw Oyster Cult is great.
Aug 9th - Preservation Hall Jazz Band at Preservation Hall. Ashamed to admit I've never actually been in the Pres Hall venue, but I've seen PHJB countless times. Classic trad jazz, as authentic as it gets. Pres Hall is a teeny tiny venue, but there is no amplification, pure acoustic music. I highly recommend it. Right in the quarter.
There is always so much going on music wise. Check out the WWOZ calendar for yourself and see if anything strikes your fancy. I don't drink either, but I always enjoy walking down Frenchmen St (the "local's bourbon st", at the back of the quarter) and seeing all the crazy people. You can wander into a lot of bars cover free and hear amazing brass band music. Don't fear the tuba.
Overall safety wise, the french quarter is generally totally safe, and the CBD is pretty safe too. Just be aware of your surroundings as you would be in any other big city and you'll be fine.
New Orleans is the fucking best.
