Several weeks ago, we were invited to Marriott's Bethesda, Maryland headquarters to meet with hotel executives and experience the "belly of the beast," so to speak - the Marriott Test Kitchen, where dishes for the chains' more than 1,000 restaurants are created, tested and perfected. For this experience, we, along with several other food and travel bloggers, offered our opinions on dishes for the chain's new "Eat. Drink. Connect." Bistro concept, which was first unveiled 2007 and is expected to be implemented across all U.S. Courtyard hotels by 2012. At present, more than 338 hotels have the Bistro concept in place.
