From my BKK experiences, the restaurants have some more options but lot more kids and families milling around. If the lounge breakfast - omelet stations, pancakes, half a dozen hot dishes, a half dozen cold dishes, Thai breakfast food (which looks like Thai lunch and dinner food to me but I digress), a wide variety of cereals, fruits, breads and drinks is a forced march, then sign me up. At least at the Marriott props, I think the lounges are the better option for breakfast over the restaurants, and I usually do have a choice of the two.
