You can almost smell the pizza cooking in the oven. Mark Bello’s “Pizza a Casa” just put up signage on Grand Street (just east of Essex). No. it’s not another place to get a slice. “It’s a “pizza self-sufficiency center.” For the full scoop, you can have a look at the story we did on the pizza cooking school and retail store last November. According to Mark’s web site, opening day is April 15th (the tax day “dough” puns can start now). Right next door to Kossar’s and steps away from the Doughnut Plant? Dangerous.
