Eating well is an investment in humankind’s future, as it gives the body intimate knowledge of the fruits and vegetables that will one day rise against us. Study the produce with today's Groupon: for $15, you get $35 worth of fresh, healthy fare at Nature's Grill. This deal is valid at all three Brooklyn locations in Caesar's Bay, Cobble Hill, and Bay Ridge.

Wielding a seemingly endless menu of fresh, made-to-order meals, Nature's Grill shapes natural ingredients into health-focused fare at breakfast, lunch, and dinner. Protein-rich smoothies and shakes ($3–$5) rebuild battered muscles following a workout or an extended bout of sitting in the middle car seat, and custom fruit and vegetable juices work to strengthen bones and lower cholesterol. Steak and bison burgers ($7–$7.25) share plate space with vegetarian-friendly tofu sandwiches and vegetarian paninis ($6.50–$7.50), and grilled tuna steak ($14.50) glistens in the reflected light of a colorful pear salad made up of goat cheese, pear slivers, mesclun greens, and fat-free raspberry dressing ($9.95). Honey whole-wheat pizzas, breakfasts hot off the griddle, and midday lunchboxes round out Nature’s Grill savory wheelhouse of recipes.

Each of Nature's Grill's three locations welcomes health-conscious consumers with warmly decorated walls painted in rich red and burnt-umber tones. Chefs scurry back and forth around the gleaming metal kitchen as they craft health-conscious fare without the use of microwaves, witchcraft, MSG, or preservatives. The earth-friendly eatery embraces the use of recycled packing products for meal delivery and calls upon customers’ suggestions to tailor an ever-expanding menu.
