The Cinco de Mayo festivities spill over in to Tuesday, May 7th at Grafton Street, where they’ll be toasting the holiday with a Don Julio tequila dinner. At 7:00pm in the restaurant’s Harvard Square dining room, chef Eric Gregory will bring out the first of four seasonally-driven courses accompanied by classic cocktails as well as a few fresh interpretations from Bar Manager Morgan Carney. Get a glimpse of the $45 menu below; it’s full of modern American fare (with the occasional nod to Mexican flavors). Call 617.497.0400.
