The restaurant of the Marriott Hotel at Lakeway Place (astride the southern foot of the Causeway), the Bistreaux functions almost entirely as a convenience for guests in the hotel and people who work in the Lakeway office building. That said, the menu gives more choices than you might expect, and even has a touch of New American hipness in its offerings, and even a French-accented dish here and there. The captive clientele allows the kitchen and dining room to put forth a bigger effort than one might expect--but at time to be less than perfectly consistent. It is not uncommon at dinner for one to have the entire place to oneself. The Sunday brunch buffet has a fairly strong following among Metairie locals.
