French pastries arrived on the corner of Ninth and K streets Dec. 8 when Estelle’s Patisserie opened without fanfare to gauge the market before adjusting and doing a grand opening sometime in January. “The customers have been so supportive,” said owner Esther Son, whose first name translates to Estelle in French. “I’ve owned other businesses, and this group down here is just so dynamic and supportive.” The staff of about 12 starts baking as early as 3 a.m., and the bakery offers about 35 items – from fruit tarts, puff pastries and croissants to soups, sandwiches and baguettes. Cream-filled puff pastries, raspberry and blueberry tarts, buttery croissants and Madeleines in various flavors
