There can be no more charming a setting for an informal alfresco lunch than smack dab in the middle of Fairchild Tropical Botanic Garden. Right by the conservatory, to be precise. A stone's throw from the rare plant section, but remember: People who dine by glass houses shouldn't throw stones. There is seating for 150 to 200 people, and a concise selection of soups, salads, and sandwiches to soothe nature lovers of all stripes. We like the feature sandwiches (each $7.95), especially panini Caprese, a baguette rife with ripe Redland tomatoes (seasonal), fresh mozzarella, and basil aioli. We are also partial to black forest ham wrapped in a pesto tortilla with dilled havarti cheese, cucumbers, and tomato. Another favorite is mango chicken salad, which lends itself to the environment in a very natural manner. So do cool "hand-crafted" tropical sodas in flavors such as tangerine, watermelon, and kiwi. These are made on-premises using real fruit concentrates and pure cane sugar, and provide a kick as effervescent as any Chihuly sculpture.
