I was there last month and the Lounge closes starting Friday afternoon for the weekend. I didn't spend the weekend, so not sure about weekend brekkie.
The Lounge is currently on the first floor next to FD. The hotel is under remodeling and some elevators were not working and some floors closed off. The Lounge had been on a higher floor, and a cocktail bar was converted into the Lounge. Not sure if this is temporary location or it will be moved back to where it was previously.
I agree the morning and evening spreads are very nice. It was very weak in the yogurt area, but otherwise very good.
