It’s been about a year and a half since the Mina Group opened the stylishly rustic Cal Mare in the Beverly Center for dinner and Sunday brunches prepared by Michael Mina’s prized protégé Adam Sobel. Starting this week they’ve finally added a delightful weekday lunch menu in the relaxed 8,000 square space and an all-day happy hour in the bar under its bright pink bougainvillea canopy . There are new and signature items on the lineup, as well as a three-course Vespa menu for $29 if you’re in a hurry.
