Riviera Supper Club and Turquoise Room at 7777 University Avenue has operated La Mesa's original grill-your-own steakhouse since 2009, inside a mid-century modern building that previously housed the Jamar restaurant beginning in 1962. The communal charcoal grill lets diners sear their own cuts—including hand-cut ribeyes and filet mignon skewers—or opt for kitchen-prepared entrées like chicken with cornbread stuffing, an interactive format without parallel among La Mesa's sit-down concepts including Limoncello Modern Italian in the Village. The adjoining Turquoise Room lounge hosts live music five nights per week on a first-come, first-serve basis, while the dining-side reservation book fills separately. Shared-plate sides include tempura asparagus, Brussels sprouts, and signature onion rings, and the craft cocktail program builds drinks around house-infused syrups and fresh-pressed citrus—a bar depth that matches the cocktail ambitions at Ney Restaurant down University Avenue. The highest-tier table orders pair a bone-in ribeye grilled over natural lump charcoal with a bacon-wrapped shrimp starter and a marinated filet mignon skewer for a multi-cut, multi-preparation steakhouse spread.
