The restaurants of The Metropolitan Restaurant Group will be donating the proceeds from their MET Tokyo Burger to the relief effort in Japan. So if you need a reason to get to any of their four restaurants – The Metropolitan Club in Chestnut Hill, Met Back Bay on Dartmouth Street, Met Bat & Grill in Dedham or Met Bar & Grill in Natick – here you have it (as if a delicious burger topped with avocado, Muenster cheese, pickled red onions, daikon sprouts, and sticky soy weren’t enough). Do some good. Book a table between now and April 1st. Call the restaurants directly for reservations or directions.
