Rockridge used to be the center of East Bay high-end restaurant culture but no more. All through last decade, the neighborhood grew older, better off — same thing that happened to Berkeley’s Gourmet Ghetto the decade before that — and things got stuffy. Oakland’s fun center shifted to Uptown, a setting more thrilling, more awesomely urban than the low, orderly storefronts of College Avenue. The Great Recession bit hard in Rockridge. The Water Lounge and Raw Bar space is still empty; so’s Citron (a recent report suggested À Côté owner Jack Knowles has plans to open a casual place there called Next Door, though the launch date is probably sometime in the second half of 2012, at the earliest).
