The sous chef squabble continues this month at Sibling Rivalry where Monday nights are Fight Night. Sous chefs Jake Smith and Simon Restrepo will duke it out on two dueling prix fixe menus, using the same basic ingredients to create unique three-course menus that reflect their respective culinary styles. Guests can choose either menu for $35 per person. Place your bets and get in on the action every Monday night (the menu will be different every week), just call Sibling Rivalry at 617.338.5338 to make reservations.
