As for Mimosas, you can have the champagne straight up without any OJ and vice versa plus there is an abundance of coffee and and other beverages.
The only thing that I can imagine as being unappealing to people is the quantity of seafood and lack of large amounts of typical American breakfast food. Americans don’t typically eat ceviche as a morning dish, and there was a lack of bovine variety options.
As for the Atrium seat, I personally didn’t sit there so I am not sure how to acquire it. Maybe asking one of the hostess’s if they can direct you.

Hope this helps
