Moonlighting for you involves illicit activity on beaches at 2 a.m. (So long, sweet summer.) For the architects and designers at AvroKo, it means building a bar and resto. And running both. Double Crown opens tomorrow a few blocks north of Public, their first restaurant. The concept is British Empire — the Far Eastern countries (India, Singapore) colonized by the English. Designwise, that means carved marble light fixtures, ceiling fans strung together with leather belts, and lots of teak. (The AvroKo special: inventive, cool, and custom built.) Foodwise, that means tandoori-marinated foie gras with Earl Grey prunes, and pheasant and licorice pie with lavender. (The chef Brad Farmerie special: mixing unexpected ingredients brilliantly.) Double your fun next door at Madam Geneva, a cozy bar with a wood-paneled ceiling and lace panels. Try not to overdo it. You have work tomorrow. Double Crown, 316 Bowery, at Bleecker Street; Madam Geneva, 4 Bleecker Street, at Bowery (212-254-0350 for both).
