Review: 13 is a delightful little place close enough to, but just outside of, the main tourist drag. I went for the black bean veggie burger, which was better than I expected (and is baked rather than fried -- a nice touch). Local brews on tap were a nice addition. The service is...let's call it Slacker Casual -- I wouldn't go there if I were in a hurry. But I didn't experience any surliness or attitude (as some reviewers on other sites have complained about); to the contrary, everyone was very friendly. 13 sits on the site of New Orleans's former only all-veg place, Old Dog New Tricks, and one of the employees told me the idea was to keep that veg-friendliness while expanding the menu to appeal to mixed groups. While an additional veggie item or two wouldn't have hurt, they certainly have succeeded in being a good destination for vegetarians combined with a very pleasant vibe. The storefront is a bit hard to find: the sign is hard to read, and up-front it looks like a bar (which it is). It's pretty dark inside, but in an attractive sort of way.
