These days, there’s a reason to make for the bar at Blu any day of the week. Chef Kathleen Smith has a different special planned for every weekday: pop in on Mondays for $4 flatbreads; on Tuesdays tacos are just $5; $4 sliders are the order of the day on Wednesdays; on Thursdays skewers can be yours for $5 each; and on Fridays freshly shucked oysters are there for the taking for $2 apiece. Pick your special or pick your day of the week and get to Blu for a bite at the bar. Call 617.259.1735 for more information.
