"This subterranean Harvard Square staple has been open since 1971; it serves pub fare, sandwiches, soups, salads, and more. The entire food menu is half-priced daily from 5 p.m. to 7:30 p.m. with a $4 minimum beverage purchase per person. No to-go bags." - Erika Adams
"This beloved Harvard Square restaurant is the perfect spot for a budget-conscious diner. From 5 to 7:30 p.m. the entire food menu is half-price with a $4 minimum drink purchase per person. That menu includes a smorgasbord of hearty fare, from brisket nachos and Tiki wings to quesadillas and potato skins." - Celina Colby

"Keep Grendel’s Den in mind for the end of the semester when you have so little money left that going to Starbucks for all three meals seems like a good idea. The entire bar menu at this comfortable little basement spot is half-off every night from 5-7:30pm. That gets you things like grilled steak for only $7, and a few salads that you can get for as low as $4. It’s not a menu that’s going to blow you away, but it’s a good little spot to hang out with some beers for a few hours before heading out for the night." - dan secatore
"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
