I had been today to the JW Marriott Marquis Hotel in Business Bay to try out the Breakfast at the Kitchen 6 Restaurant on the first floor. The JW Marriott Marquis is the tallest Hotel Towers in the world just slightly lower than the Empire State Building in New York with 355meters of height.
Kitchen 6 offers you 6 different live cooking stations in its all day dining setting. It is an international buffet featuring Asian woks, Middle Eastern grills, European breads and Indian tandoors. The Restaurant itself is so huge you have to walk quite some to see all stations and try them out. And I highly recommend to check out all of them if you are there.
The breakfast comes in at 140AED per person which is reasonable considering what you get. Only thing I did not see was a pork section, but I might have just overlooked it given the sheer size the Restaurant has.
