If you’ve pretty much never met a burger you didn’t like, Mondays are your lucky day at Met Back Bay. Every week between the hours of 5:00 and 10:00pm, you can choose from three options from the burger bar for only $4.99 each. These MET standards include The D.C. with American cheese, lettuce, tomato and mayo; The Manhattan with Swiss, mushrooms, bacon and special sauce; and The Mexico City with guacamole, charred tomato salsa, cilantro and jalapenos. All these bad boys get served on a sesame seed bun and are just as delicious at half their usual price. For more information or to make reservations for an upcoming Monday (or any day of your choosing), call 617.267.0451.
