"Very, very busy. We've had a couple of buyouts. We've had about five parties per week," said David Hanna, of Waterbar Restaurant.

Liz Curtis is the CEO of Fulcrum Group, a Bay Area events company.
She says the new omicron variant is already impacting her business.

Christopher Rivera works at Coqueta on San Francisco's Embarcadero.
He says his restaurant has hosted several holiday parties where only a fraction of those meant to come actually show up.
"We had a lot of events where, you know, let's say if it was a party of 20 that were coming in, and then six of them would show up because five of them got COVID and the rest of them were exposed," Rivera said.

And with the uncertainty surrounding the new variant now lurking over the industry yet again, Rivera says he's just thankful that the holiday parties they have had have been a success.
"With omicron, things might slow down again. So thank God we were this busy for almost the whole month of December because I don't know what January is going to be like," said Rivera.
