Where is Grand Lux Cafe nutritional information?

It's not available, but I believe in certain states -- perhaps New York -- it can be requested. Grand Lux is a Cheesecake Factory restaurant, and Cheesecake Factory doesn't share their nutrition information either.

However, there is a site that lists partial nutrition information for Cheesecake Factory items, and several items on Grand Lux's menu are similar, if not identical, to Cheesecake Factory. For example, the Luau Salad at Cheesecake Factory and the Polynesian Chicken Salad at Lux are almost identical.
