It's expensive, and there's quite a long wait, but it's great food when all is said and done. Definitely a once-in-a-while spot, but also a worth-it spot. Some people would say it's a must-try, but if you're not in to wood-fired pizza, it will have little for you.
They do what they do, and they do it well. Both things to keep in mind if you're thinking of hitting the place up :)
