Cafe Spiaggia is the easygoing younger sibling of Spiaggia, the upscale Italian restaurant down the hall. In the cafe, chef Tony Mantuano tones down the cost, but not the devotion to simple, seasonal food. There's no dress code, but the neighborhood regulars do radiate a certain ready refinement. The dining room glows with modern Italian furnishings, a marble floor and dramatic 15th Century frescoes reproduced from an Italian villa in Mantua, Italy. Hand-blown Venitian blue glass light fixtures complete the traditional yet modern vibe. Some tables offer a dramatic lake view, as at Spiaggia.
