Hi Gophers13,
Welcome to NYC! Yes, the best place to watch is at Arctica and they have had viewings the last few years for the games. For the big games there is a decent turnout, but for some of the non-con games the turnout can be sparse. I try to go for a couple of games a year and just watch the rest at home (damn Time-Warner just raised the rates again for me to watch the Gophs!).
I work near Arctica and just went past a few weeks ago. Seemed to be business as usual. Best place to get updates on the game watching is the University of Minnesota in NYC Facebook group page. I think there is also a listserv with event updates.
