Any recommendations for casual lunch near Sofitel?
Walking north up to La Cienega and Melrose (~10 minutes), I'm a big fan of Taste on Melrose, east of La Cienega.
West from La Cienega, you've got Urth Caffe-- sandwiches, salads, great coffee and pastries, and a scene-- and Le Pain Quotidien (of which I am NOT a fan but many others are).
Breadbar, Joan's on Third, Lemonade [9001 Beverly @ Almont] and Little Next Door are all relatively close, though, of the four, only Breadbar and Joan's would probably be considered walkable by most.
