The Marketplace Cafe, at the Poponesset Marketplace, is a sister business to the Raw Bar.  You can even order food to be delivered to your table at the Raw Bar.  The Cafe has it's own indoor and outdoor seating as well as a "wine bar" and a pretty decent menu. 

Unlike it's neighbor which has a colossal traditional lobster roll (mayo based), you can get lobster rolls your way at the Cafe - differetn sizes as well as a warm lobster roll with drawn butter.  

Hours and menu are seasonal, so check the website if visiting off season.
