E.S.B. Cafe is a coffee kiosk founded in 2019 on Encinitas Boulevard at the corner of Calle Magdalena, serving Mexican-inspired espresso drinks from a walk-up and drive-through window in Encinitas. The drink menu features horchata lattes from a house-blended rice-and-cinnamon base and mochas made with hand-ground Mexican chocolate, a heritage-recipe approach to specialty coffee distinct from the all-American egg-sandwich format at Breakfast Republic on the same boulevard. A triple-steep brewing system produces three distinct cold-coffee options: a 12-hour iced coffee, a 24-hour cold brew, and a 36-hour nitro cold brew, each developing progressively deeper extraction profiles. House-made syrups replace commercial flavorings across the full drink menu, including seasonal offerings like rompope lattes and spiced pumpkin builds. Homemade pastries including banana bread and croissants round out the morning food program, extending the Encinitas Boulevard breakfast corridor toward Cardiff-by-the-Sea where VG Donut & Bakery anchors the bakery scene. The 36-hour nitro cold brew processes through a nitrogen-infusion tap system that produces a cascading, stout-like pour with a naturally sweet, creamy mouthfeel absent any added dairy or sugar.
