All I've ever heard about Sona is that the chef is an up and comer. At some point, that probably stops being true, and the fact that I haven't heard much more about the restaurant hasn't persuaded me to try it.
I'd NEVER heard about A.O.C., but did a bit of research and was shocked to find that it is within two miles of my office. Check out this local restaurant blog.

A.O.C. is covered about three restaurants down. Granted, this is one (other) person's opinion, but it will add to your knowledge about the restaurant. Further down in the blog, the writer covers the Edendale Grill. That is a phenomenal restaurant experience, a converted fire station serves as home to tremendous food. Tough to get to without a car, but worth it.
