INDIANAPOLIS—Looking to experience the kind of timeless, romantic atmosphere that only a ring-shaped, 50-foot-tall, motorized eatery can provide, millions of lovers flocked to the nation's roughly two dozen revolving restaurants this Valentine's Day. The couples—whose deep love for each other could only be expressed by consuming an overpriced meal near a large window while traveling almost imperceptibly around a fixed circular path—packed panoramic restaurants from New York to Seattle. "The wife and I saw the whole town," said Howard Watts, who visited the Eagle's Nest restaurant in Indianapolis with his spouse, Sheila. "The Motor Speedway, the interstate. Everything. Making one full rotation every 47 minutes reminded us why we fell in love." According to analysts, the nation's singles were still happy to spend the holiday microwaving things that can be eaten over the sink.
