Thanks to heads up from fellow Chowhounds last week re B opening I stopped by for lunch today. It's their first day. Located on corner of 9th and Washington across the street from Ratto's. They've kept the lovely mosaic floor from the original cigar (?) store and, as celery noticed, added lots of nice sidewalk seating. Staff was knowledgable and friendly. I got grilled chicken salad to go--lots of grilled chicken on organic greens w/ roasted red peppers, grilled onions, tiny yellow and red cherry tomatoes, bacon, apples and chevre. Delicious and nice portion for $8.50. Rest of menu looks very promising, too.
Hope they're able to break the bad luck of all the previous restaurants at that location.
