The mellow Sempione Park scene picks up the pace after sunset at Just Cavalli Restaurant & Club, where fashion designer Roberto Cavalli has created an ultramodern glass temple of cool, perfect for the see-and-be-seen crowd. The best time to go is in the summer when the outdoor Just Flower Garden lights up with torches and candelabras. Claim a sofa and spend the evening sipping designer cocktails accompanied by fresh antipasti while the house DJ mixes downtempo grooves.
