You will find a wonderful buffet breakfast served every day
They do, a good buffet in the lobby
For sure you can reach cheaper options in downtown but I prefered to start up the day there and then make no stops and keep walking in the city
They do offer breakfast for a fee but i find it convenient to just get breakfast at shops along the way to the metro station. Cheaper that way.
