Koko's serves Latin American, Mexican, and Salvadoran cuisine such as burritos, enchiladas, fried plantains, guacamole, tacos, and tortilla soup, and has garnered a positive reception.

[10][11][12] The restaurant has also served a "Mexican poke bowl" with yellowfin tuna, mango, and edamame, as well as carne asada and chicken flautas,[13] tortilla soup,[1] guacamole, and a cucumber-cilantro margarita.

[6] During the COVID-19 pandemic, Koko's pledged to donate thousands of burritos to support food programs in the area, in collaboration with the Seabrook Community Foundation.

In Moon Olympic Peninsula, Jeff Burlingame said the coast location "offers great food in a fun setting" and called the menu "both fresh and a little different".

[17] In a similar 2024 list, the magazine's Allison Williams and Allecia Vermillion said Koko's has the "ability to wield American influence (kale salad, a chorizo burger) without dumbing things down".
