Serra by Birreria’s whole thing is changing their decor with the seasons, so this rooftop restaurant at Eataly Flatiron is the first spot we seek out when we want to live inside a postcard. This year the look is less Frozen and more lightly frosted. Instead of evergreens, you get sage, icy lavender hues, and red winter berries that look like ornaments made by Mother Earth herself. No Santa-shaped drinkware here, but this is an ideal spot to come eat a warm bowl of housemade pappardelle and wild mushroom ragù and pretend you’re in the Italian countryside.
