We had a reservation and arrived just before the place opened. There were lots of super aggressive tourists that pushed their way to the front of the line, so don't be afraid to be assertive.
The steak portions are so large that I would suggest ordering one steak for every two people. Even the loom had four pieces per order. The food was very good, but not better than Ruth's Chris. The service was also not great, but it's worth going for the experience and a nice meal.
