"Serra by Birreria’s whole thing is changing their decor with the seasons, so if you’d like to live in an Italian countryside calendar, seek out this rooftop restaurant at Eataly Flatiron. Their winter theme is more subtle than other spots on this guide: Instead of evergreens, you get a calming canopy of eucalyptus, strung with delicate white lights. No Santa-shaped drinkware here, but you can order panettone served tableside with your choice of housemade mascarpone or chocolate sauce." - neha talreja, molly fitzpatrick
