"As a general rule, we kept Happy Hour specials off this list. Nine times out of ten when you go out for Happy Hour, you show up with some co-workers for $2 tacos and end up leaving $50 poorer several hours later, because you couldn’t keep yourself from ordering too many margaritas and several non-discounted plates of nachos. Grendel’s Den, an underground pub in Harvard Square is the only exception we allowed, because they don’t discount just a few appetizers for Happy Hour, they discount the entire menu. Every day from 5-7:30 absolutely everything is half-price with the purchase of one drink." - dan secatore
