I normally get almond milk but their soy milk was so much better than I thought it would be! Subtle and packed with plant protein 🌱 ### sauceontheside — 4.3/5 · Oct 11, 2025 Iced cortado for a quick pick me up! ### airiseats — 4.3/5 · Feb 21, 2026 I ordered the horchata latte hot because I wanted something warm on a rainy day but it wasn’t that sweet at all and only tasted like cinnamon. The Biscoff latte was much better and it’s cool to know that they make their Biscoff syrup from scratch in house.
