I ate at the C's restaurant last Sunday, for their Deluxe Sunday Brunch. As far as I know, this is the most expensive Sunday Brunch in Jakarta.

Cost is 700,000 IDR++ per person. It includes free flow soft drinks, juices and Pellegrino water. This works out to $64 a person with tax/service, or half that if you have the Club at the Hyatt card, if you dine with 2 people. Smaller kids under a certain age are free.

They have a nice selection of shellfish, including huge shrimp, lobster tails, some clams and I think oysters. I think this buffet only makes sense if you are really into the seafood.

They do have a few types of beef, and lamb. I arrived the last hour of the buffet, so I had them warm up the meat for me, which was much better. I really enjoyed the T-bone they had.

They have a limited selection of Dim Sum, different Chinese options, Peking Duck pancakes, and some Indonesian selections. Everything was halal here, so no pork options.

You can also add a free flow champagne/sparkling wine for an additional fee.

I was so stuffed on the beef and lobster tail, that I barely tasted the nice ice cream selection, or any other desserts.

I'd recommend showing up nearer to the noon start time, to get the items fresh. I'd rate it 4/5*. If you want a special Sunday only brunch, it's good to check it out. The price is steep, certainly, so I'd be hesitant to go if I didn't have the Club at the Hyatt card for the 50% discount.
