Brisbane is set to get an over-water champagne and oyster bar but the developer is remaining tight-lipped about who the operator will be.

The bar is to be built as part of the $110 million Howard Smith Wharves project, with the development application for the bar submitted in December 2017 and approved in April 2018.

On Tuesday it was revealed the construction of the over-water bar was now under way, but Howard Smith Wharves development director Luke Smith would not give away any more detail.

Mr Smith confirmed the operator had been selected, and was a known operator, but would not elaborate further.
