The newest entrant into the LA coffee scene is a Seattle import: Caffe Vita. Caffe Vita has numerous Seattle shops along with a couple in Portland and one in Manhattan. They recently opened right at the Sunset/Hollywood/Virgil intersection in the space that used to be the hipster junk shop Uncle Jer's.
I enjoyed their espresso, which I found a bit less acidic than some of the others in town, though the lack of acidity that makes for a nicer espresso makes for a bit blander of a milk drink. That being said, it's quite good and a welcome addition to the local coffee scene.
