Hotels near the freeway aren't normally hot spots for salsa. But Coco Locos, on the second floor of the Ramada Inn on Marina Mile Boulevard, makes short work of skeptics. The Caribbean sounds that blare from the DJ booth can turn the shy footloose, and by midnight, everyone's on the hardwood dance floor under the raspberry- and lime-toned strobe light. Señoritas get in free before 11; those looking to learn salsa moves will find obliging gentlemen. And should you have too much to drink, or wish to have your next dance horizontal, you're already at a hotel.
