Nothing like a little hint of truffle to take a dish up a notch. You’d think it’d be hard to find on menus during Restaurant Week Boston but it makes more than a few appearances in quiche and mac-and-cheese, dressings and decadent cream sauces. See below for a handful of restaurants that are adding the luxurious little fungi to their prix fixe offerings.
