Kei Coffee House

Having already demonstrated its prowess with everything from upscale Vietnamese to Peruvian Chifa cuisine and Italian-Japanese fusion, Kei Concepts opened a long-gestating venture in summer 2024: a gourmet coffee shop in Westminster, a block or two away from its cluster of Fountain Valley restaurants. Since then, Kei Coffee House has evolved significantly, expanding both its hours (8am to 10pm, 7 days) and menu items to offer a wider variety of food and drink options. Given its trajectory – and Kei’s expansions elsewhere – the only surprise is that second and third locations haven’t yet been announced.

From orange jam-enhanced Thai tea to melon espresso tonics and matcha toffee drinks, Kei Coffee House has canvassed and expanded upon regional beverage recipes with pretty much uniform success. Over the course of its first year, the core of the drink menu has settled into matcha-based teas, sweetened milk espresso/coffee drinks, and soda-based refreshers; fresh fruits, ground nuts, and creamy foam toppings are common. Seasonal drinks are also important, and have included butterscotch lattes, spiced apple lattes, and orange mochas – the latter particularly terrific. In summer 2025, Kei introduced Korean hotteok coffee and tea drinks with roasted sesame seeds, cinnamon, brown sugar, and walnuts, another unexpected winner.
