Founded by Executive Chef Nick Balsamo, a U.S. Army veteran with more than 15 years of culinary experience, Rosemarie's Buns & Brews is an American restaurant and hamburger spot at 3852 Mission Blvd in Pacific Beach (92109). The restaurant started as a mobile food truck that earned coverage in the San Diego Reader before Balsamo opened this first brick-and-mortar location in Mission Beach. The concept has since expanded to Ocean Beach and Encinitas, with Balsamo intentionally choosing neighborhoods rather than pursuing a franchise model. The business identifies as both Asian-owned and veteran-owned. Rosemarie's earned a spot on Yelp's Top 100 Restaurants in the United States, a distinction backed by a 4.7-star Google rating across more than 725 reviews. The menu centers on Wagyu beef sliders with onion confit, American cheese, special sauce with Kewpie mayo, and pickle on a brioche bun, alongside duck fat Nashville hot chicken and softshell crab sliders. Mission Blvd regulars catching live music at 710 Beach Club often stop in at Rosemarie's for a post-show meal. Balsamo trained in Asia and has worked alongside renowned chefs throughout his career, which shows in the precision of each slider. The restaurant is dog-friendly with indoor and outdoor seating, offers catering, and accepts reservations. Those exploring the beachfront dining scene along Mission Blvd will also enjoy the Mediterranean-influenced plates at Costa Brava a short walk away.
