Carrot Flower, a new smoothie, salad and juice bar, opened this week. The new café took over and completely renovated the Centre Street space long occupied by antiques store Cobwebs. Smoothies ($8), which are all dairy- and gluten-free, read like a who's who of healthful ingredients. They include the Green Street Tea with pineapple, spinach, matcha, lemon and coconut water; the Monkey Gone to Heaven with blueberries, banana, peanut butter, honey and coconut milk; and Pear Ubu with pear, kale, banana, almond butter and almond milk. Fresh juices ($6 to $7.50) are similarly packed with healthful ingredients, such as the Kurious Oranj with orange, carrot, ginger and turmeric; the Serious Green with kale, spinach, celery, lemon, ginger and mint; and the Beet Happening with beet, apple, carrot and ginger.
