Charlestown’sCharlestown’s 10 City Square holds a special place in Boston restaurant history. For nearly two decades, it was the site of notorious celebrity chef Todd English’s landmark restaurant Olives, at one time a line-inducing spot that drew people to Charlestown from all over the city.

After a subsequent turn as Legal Oysteria — an Italian restaurant run by the ubiquitous seafood chain Legal — and years of pandemic vacancy, the building is once again drawing crowds of eager diners. The crew behind Charlestown hangouts Monument and Waverly — as well as a small South Boston empire that includes brunch hotspot Lincoln and Italian restaurant Capo — have launched Prima, an Italian steakhouse with veal chops, piles of pasta, a mozzarella bar.
