Located in the busy tech center of Sorrento Valley, Zumbar Coffee is a diminutive shop with a huge reputation for serving some of the best coffee in the area. Taking a craftsman’s approach to roasting, they have perfected the process using a vintage, cast-iron coffee roaster situated right behind the ordering counter, giving every patron a chance to see/hear the action. A small selection of pastries and breads are also available, delivered from VG’s Donuts and Opera Patisserie every morning. Some regulars believe that the coffee actually advances science, and I have to agree, given the buzzing conversation during my last visit. They also sell fresh-roasted beans at the shop or online, so you’re never too far away from a great cup of joe.
