Try the Burbon Street Blues Club (BBC) for inexpensive booze. Three-for-One during the day, and Three-for-One upstairs all night. BTW, the upstairs thing is not advertised. As far as Food, The Gumbo Shop is always a good choice. If you like good pizza, try the Mona Lisa
http://monalisa.neworleansfanatic.com/ . It's easy to find, just ask some locals in the Quarter to point you in the right direction. Have Fun!
