Launched in 2014 by two Europeans—one British, one Swiss—Buda Juice is our most Spartan sanctuary of meticulously organic, cold-pressed juice. The juggernaut that started with a fridge in a Plano coffee shop now has a warehouse space in the Design District, a frigid kingdom at 35 degrees. From the minimalist menu, beginners might reach for Valencia orange, the gateway. The hardcore will brave the detox cleanse—a prescribed sequence of green juice, cucumber lemonade, a lovely gazpacho and the reward of almond milk. One day, three days, five days and the world feels clarified.
