At GH Bali, if you have globalist breakfast included, you may go to any restaurant that is open for breakfast, I asked.
You are not restricted to the Grand Club Lounge breakfast. However I find the offerings at the Club Lounge breakfast to be perfectly fine while the atmosphere is nice amidst the lake and there is a Quiet Zone. Service at Grand Club Lounge has been lacking a bit, it has been busy over Easter. Egg station was overwhelmed at times and slow to take orders, etc. It was better before Easter so I don't think this is a constant issue. Can't really complain since I received a suite upgrade to a suite that even includes a full kitchen with stove, microwave, toaster, freezer and full size fridge which is pretty neat considering the cheap rate I booked and it's a stay longer than 7 days without having to use a SUA.

Can confirm that the suite initially had a bit of a moldy, damp smell that I perceived to originate from the aircon. I saw staff in the hallway carrying an electric essential oil diffuser so I assume that if you complain they can bring you one. The first two days I tried to air the suite by opening the doors and it helped. It has improved after the first to days. The humidity is simply high here. If you handwash clothes, the Grand Hyatt Bali provides a clothes rack for the balcony which is useful. Clothes hardly dry overnigh though. It takes more like 2 days for swimwear and exercise clothes to fully dry so pack accordingly.
