Babak Bina poured wine last week at the bar of the new restaurant he opened with his sister Azita Bina-Seibel at 26 Charles Street. Bina said the concept behind “Bin 26 Enoteca” (“eno” references wine while “teca” means bar) is to have fun and relax in a friendly environment, whether stopping in for a single glass of wine and a bite of food or for a special occasion dinner. The wine book has 150 selections from around the world, with 50 wines sold by the glass. Azita, executive chef, will oversee the preparation of seasonal menus reflecting the different regions of Italy. The restaurant will he open for lunch and dinner seven days a week.
