In Dallas, Texas there are many choices for hotels, but none perhaps as large as the Anatole. Walking into the building and looking up is an experience in and of itself. What a huge building. And you are having a mega conference with many different people, there are few places that you could go to that would be better suited. The restaurant at the top, Nana would be an awesome place to have a small scale type of event. There is a great view from up there (especially for Dallas) and the food is truly excellent. Putting a jazz trio up there or a Tony Bennet-type performance would be a big winner.
