Just off Calle Azacayas, duck down the spooky alley, cross the small patio and battle with the hefty door to slip into one of the best jazz and flamenco haunts in the city, with local musicians coming down from Sacromonte to jam. But the party doesn’t get rolling till at least 1am, and that’s on weeknights. There’s a good formal show (earlier) on Sunday nights, if you can’t stick it out till the wee hours.
