Want to impress your amor? Take him or her for a night out at Santos Lounge. Hidden behind Frank and Lupe's Mexican Restaurant, it's an arty sort of nightspot, where the walls are painted with deep shades of red and yellow and the rooms are populated with a funky collection of trinkets, stained glass, and antiques. In fact, the place is reminiscent of a gigantic Day of the Dead altar, filled with artwork and such ofretas as ornate crosses and skull statues. Inside, the bar is stocked with a dozen different tequilas and a host of south-of-the-border beers, while the outside is dominated by yucca plants and murals.
