For winter-weary, snow-fatigued Bostonians, here’s a little something to look forward to: prix fixe menus! From March 1st through 6th and then again from March 8th through 13th, more than 150 restaurants will be offering multi-course menus for $15, $20 or $25 at lunch and $28, $33 and $38 during dinner. Spend your next snow day perusing menus and booking your tables on the Insider’s Guide.
