The recent annual meeting in Copenhagen of the Committee to Study Things That Nobody Cares About yielded surprising yet, as always, unimportant news: Salads, smoothies, and other healthful foods are perceived by our taste buds to be more flavorful and satisfying when eaten in natural surroundings. The folks who funded these fictitious findings were fans of T.H.R.I.V.E., a raw/vegan restaurant located in the midst of the Garden Center in South Beach. There are a handful of lunches offered each day, including a daily bowl of cooked food and raw dishes. But one of three good reasons to eat here are the salads, with red, ripe tomatoes and other fresh produce — deliriously delicious when drizzled with tahini dressing. Smoothies ($6 to $7), whipped up with luscious local fruit, compose the second. Number three is the spacious and secluded dining patio, a green oasis in sync with the green food. And you don't need a committee to know that's the way it's supposed to be.
