Downtown Crossing is stepping up its epicurean game. Sibling team Azita Bina-Seibel and Babak Bina, of Lala Rokh and Bin 26 Enoteca acclaim, now bring Bina Osteria (581 Washington Street, Boston, 617.956.0888) and Bina Alimentari— a contemporary Italian restaurant and adjacent gourmet food shop, respectively — to the ’hood. At Bina Osteria, executive chef Brian Konefal and his wife and pastry chef Paola Fioravanti create homemade charcuterie and sweets. The restaurant boasts columns, an umbrellalike vaulted ceiling, and large windows with handmade curtains — not to mention a weekend brunch served until 3 p.m. Combine all that with the take-home specialty breads, pastas, and gelatos at Bina Alimentari next door, and you just might be wondering where these two spots have Bina all your life.
