Stepping into Beaucage is like happening upon a photo shoot. Women who look like supermodels simultaneously answer phones and take your name while urban beats pulse in the background. White transparent curtains sweep across giant front windows down to a shiny wood floor. Clients in black smocks recline on modern furniture, their hair in foils and paper while reading ritzy fashion magazines. Black-clad stylists fuss over women toting expensive Gucci bags, tattooed 20-somethings and foreign college-age girls. haircut here is a must, thanks to master stylists who take time for personal instruction in the art of blow-drying and styling (and who are very receptive to your personal preferences).
