Surry Hills pioneer Bar H is closing the book on its innovative Asian menu and shutting its doors for good on April 18..

When the bar-restaurant opened in 2010, former Billy Kwong head chef Hamish Ingham and partner Rebecca Lines stamped the moodily lit corner venue with a mix of urban cool and "Japanese-style Chinese food" with a sprinkling of native ingredients.

Shortly after opening Banksii at Barangaroo, Ingham and Lines sold Bar H in early 2017 to brothers Anthony and Julian Izzillo, the former shareholders in Wildfire Restaurant and current owners of De Vine Food and Wine in the Sydney CBD.

"We had a crack at it, but we're Italians," Julian Izzillo told Good Food.

He also cited a continually growing pool of Asian restaurants in the precinct, Chin Chin and Japanese pizza bar Sash just two of the arrivals.

The Izzillo brothers will give the space a complete redesign and reopen in July with a new name and Italian concept. "It'll be unique, a first in Australia," he teases.
