No doubt the weather’s been a bit wacky this winter. One day it’s freezing, and the next it’s unseasonably mild with temps soaring into the mid-fifties. Is climate change to blame for these wild fluctuations? Possibly. But even if it is, there’s a silver lining. Cuba Libre, for the second day in a row, is pricing its empanadas according to the forecast’s high temperature. Today that’s 54 degrees, which means they are 54 cents a piece from 5 to 7 p.m. And if the mercury plunges? Not to worry, Davio’s is pledging to serve its cheesesteak spring rolls for free during happy hour every time it dips below 32 degrees this winter. So no matter which way the weather goes, there’s something to look forward to.
