Rock Bottom Restaurant & Brewery, which has been operating at 8980 La Jolla Village Drive across from the UC San Diego campus since 1998, has shuttered.

The brewpub was owned by CraftWorks Holdings Inc. of Nashville, Tenn., which operates several casual-dining restaurant chains including Gordon Biersch Brewery Restaurants. Gordon Biersch’s Mission Valley site closed last summer.

CraftWorks Holdings operates nearly 400 restaurants, brewpubs and entertainment venues in 40 states.

The Wallstreet Journal recently reported that CraftWorks Holdings Inc. was on the verge of bankruptcy, which likely led to the closure of Rock Bottom’s La Jolla location.

Reasons recently provided to Rock Bottom La Jolla employees by management for the brewpub closure included lack of sufficient revenue generation and lease issues. The company operated a second Rock Bottom location in downtown’s Gaslamp Quarter from 1999 until 2013.
