Friday Night Bites: tables for two at Rose and Sons, John and Sons Oyster House and Ursa

It’s 4 p.m. on Friday, and you don’t have a dinner reservation. Still, there’s no need to fret (or waste your night waiting for a table). We just called some of the city’s hottest restaurants and found three that can squeeze in two for dinner tonight. Now it’s up to you to get dialing and snag a table before they’re all gone. Today: Rose and Sons, John and Sons Oyster House and Ursa.
