Tried the Bistro breakfast at a CY in CA last year - I'm not impressed at all. I ordered a dish with avocado in it and after I got it I found no avocado in it, after I complained they said they ran out of avocado - why don't they just say it upfront? The food was ok, nothing special - put it this way I'll never buy if if I have to pay for it.
Marriott is trying to make up the "free" breakfast by giving is Plat a free market place item.
