Who says you can’t have fun on Mondays? Certainly not Boston Magazine. In fact, they are so devoted to kicking off the week with a bang that they’ve started Mix It Up Mondays where every week from February 4th through March 11th, a different group of Downtown restaurants will offer special deals on menu items and custom Belvedere cocktails. Tonight’s inaugural mixer features Avery Bar, Avenue One and Petit Robert Central, but you can expect to see other eateries like Artisan Bistro, blu, Silvertone and Woodward get in on the fun as well. Check back here to see who’s slated for delicious, discounted downtown eats this week.
