Let’s face it: Everyone wants to stuff their face with fast food sometimes. But we don’t want to feel like crap afterward. And that’s when you drive/bike/bus/walk/crawl to North Berkeley for Nature’s Express. Not only are all its offerings completely vegan, but the place also has special menus for the soy-, wheat-/gluten-, and nut-sensitive. In this case, vegan doesn’t just mean glutinous meat substitutes. Its classic rewind “burger” (lentil patty) is delicious, flavorful, and hearty, and, when wrapped in a blanched collard leaf, almost makes you feel virtuous. Tack on an order of baked sweet potato fries (if you’re lucky; they sell out routinely during lunchtime) and a 5 a Day smoothie (kale, cucumber, beet, celery, apple juice, banana, and strawberries), and you’ll get an injection of post-lunch energy, not sluggishness. Your body will thank you. And then you can order a gluten-free brownie.
