Like fairies, hamburgers are famously difficult to photograph because they can take thousands of forms and wear a variety of sauces. Take a mental picture with today's Groupon: for $6, you get a burger entree at Lilee's Public House in Brunswick (up to a $13 value).

The grillers at Lilee's Public House press patties of 100 percent all-natural beef from Maine's Caldwell Farm in addition to flipping up gourmet vegetarian and pescatarian burgers. Traditional taste buds can savor the familiar flavors of the basic burger ($9) draped in choice of american, swiss, blue, or cheddar cheese, and the bacon-and-blue burger ($12), showered with crumbled blue cheese and crispy bacon, climbs to the haughtiest of mouthspectations. Summon the fresh-ground-lamb burger ($13) adorned with feta and secured on a grilled bulkie roll, or wet your fangs for the Atlantic salmon burger ($11), crowned in spinach, red onion, and feta and slathered in cilantro mayo. Vegetarian diners can nosh a mushroom burger ($8), with a hearty, house-made round of wild mushrooms and rice smothered in pub cheese. All burgers come accompanied by a pickle and pasta salad, fries, or coleslaw. Locally crafted sodas and beer bombard people with more flavor than a halftime speech by Snoop Dogg.
