Sorry glenngpr the buffet selection mentioned is in The Haven restaurant which is open only to those passengers with First Class lounge access.

Business Class lounge has the Noodle Bar with hot noodle dishes requested from the servery, as well as a range of drinks, ice cream, sandwiches, pastries and usually there is a hot dim sum option available. There's also the Long Bar which I assume serves alcoholic drinks and in the Pier, the Juice Bar featuring freshly made juice.
