You can't find happy hours in MA, it's illegal. However, many places have app specials from around 3pm-7pm. Unfortunately, most places on rt1 are so..so. So here's some picks:
Prince Pizza, just average.
Mt. Vernon, barely average
Angela's Woodfired Pizza, OK
Kowloon's, OK Chinese
Bertucci's Pizza, average
Donatello's, average Italian
Get the drift, nothing much to rush to.
if you are simply looking for a good time and nothing "fancy" u could try The Border Cafe Rt.1 North in Saugus...or a little further up Rt. 1 there is another Tex-Mex place that just opened up with in the last year called Fat Cactus in Lynnfield nothing says "happy hour" like a margarita and fresh nachos w/ salsa!
