Start your day with an espresso at Pavement Coffeehouse, then get some fresh air as you hike the trails at Middlesex Fells Reservation. When it’s cold outside, do power yoga at Studio U instead. Meet friends for dinner at local institution Alfredo’s, where you should try the puttanesca with fresh pasta. Skip dessert in favor of a scoop of delicious peanut butter ice cream at vegan ice-cream shop FoMu, then catch an independent movie at Coolidge Corner Theater. When you want to let your hair down, check out Allston’s music scene with a gig at Brighton Music Hall, or go dancing until late at Great Scott.
