The coffee
Branch of S3’s creativity-led coffee program, centered on handcrafted espresso, cold brew, colorful seasonal lattes and ceremonial Uji matcha.
The Escondido shop carries S3’s flavor-forward coffee identity into a downtown storefront. Public materials support handcrafted espresso drinks, cold brew, pastries and changing specialty beverages, but do not publish branch-specific beans or brew parameters. The strongest current differentiator is the 2026 move to ceremonial Uji matcha across both S3 locations.
