Zimzala restaurant at Cronulla was awash at high tide last night as waves crashed over the Esplanade.
But, after an early-morning clean-up, the restaurant was operating today as normal.
"There was no damage; it was just a matter of mopping up," joint proprietor Rebecca Nelson said.
A video of the big seas, shot by Sham Watkins, was posted on Zimzala's Facebook page with the message: "We are open - all cleaned up!!! Great entertainment down here!!! If you can brave the weather."
