Tim Connors, former owner of Readers' Choice Award winners Pini's Pizzeria in Somerville and Waltham, recently opened Andrina's Pizzeria on Massachusetts Avenue in Arlington. Unique to Andrina's is the wide variety of sauce choices for the pizzas and wings. Pizza sauces come in varieties such as picatta and creamy parm, and the wing sauces include choices such as orange ginger and jalapeno ranch. The specialty pizzas are a draw, and its thin crust pizzas are available with a gluten- free crust.
