Because we are such dedicated journalists who selflessly strive to bring you every bit of New York food news we can get our hands on, we stood in line for 45 minutes today to try the ice cream sandwiches from the city's latest food truck, Coolhaus NY. The L.A. export is handing out Firefox-themed treats for free all weekend. Is the wait worth it? For the cookies, yes — the chocolate chip ones are fabulously buttery, with lots of salt to balance out the sweetness. As for the ice cream, our vanilla scoop, despite copious flecks of bean, just couldn't stand up to the cookie, and its flavor was lost to the butter. But whatever! They're free all weekend, so we highly encourage you to try the other flavors (Earl Gray ice cream on brioche cookies, Nutella ice cream on oatmeal cookies, and blood orange sorbet on chocolate cookies), and report back. They'll be at Bryant Park tomorrow, Union Square on Sunday, and Madison Square Park on Monday, from 12–4 p.m. each day. Follow them on Twitter for updates.
