While the Señor Grubby's brand started in 2008, We proudly opened a new location in Oceanside, California in 2019. Señor Grubby's was founded by a group of local guys looking to put a twist on the local Mexican fair. After numerous trips to Mexico and local Mexican & American breakfast spots, they noticed missing elements that they wanted to highlight. Señor Grubby's is located in the heart of downtown Oceanside, California within a short walk from the Oceanside Pier. Just north of the Oceanside Harbor, Señor Grubby's, California grub Mexican restaurant, is considered a local favorite for many of Oceanside's residents, This Mexican restaurant offers delicious and unique Mexican food, beer, and wine. Providing a casual fun setting for families and friends of all ages you’ll find yourself smiling more with every visit.
