Authentic Mexican is hard to come by in Boston, but this taqueria puts up a fair fight. The picnic tables with umbrellas and the cozy, off-the-main-road location are reason alone to try out the eats on a warm day. Order chips and salsa for an afternoon snack, or the fish tacos for a cheap dinner. Beware: spicy means spicy. 92 Peterborough St., Boston, 617-262-9090, elpelon.com.
