This is a great place to have cafe au lait and beignets. It is both charming and picturesque especially at night. Forget Star Bucks experience a real coffee house/cafe for about $5 a head.
It is a safe venue with ample visitors and security so do not be afraid to go there at night. In fact at night it is even more charming. It is also open 24/7.
Only caveats bring cash (no credit cards are accepted) and when crowded (which is often) it will be noisy. However, if you sit outside on the covered porch the noise is not a problem.
