There's no end in sight to Angelenos' jones for coffee. First came the art house cafes with fancy drip, then the blockbuster chains with industrial capacity. Now we've hit a moment of refinement, with cafes as serious about their beans and their brews as beat poets are about their message. A Caffe Luxxe, only espresso is served. Co-owner Mark Wain uses one blend of beans to coax the maximum sweetness into a ristretto (short espresso), and another blend, with enough body to stand up to milk, for a latte or a cappuccino. That's the kind of specificity we like to savor.
