Jody Adams keeps it casual on Sunday nights at Rialto. The award-winning chef has unveiled a low-key, end-of-the-weekend treat for her bar diners. Each week her kitchen team will be offering up a toothsome take on the Rialto burger (the original – which comes with provolone, house-smoked bacon and a pile of hand-cut fries) for $10. The R Burger, as this mystery burger is known, will be enhanced by a rotating array of toppings, depending on the chefs’ whim. Pair it with a beer or a bottle of wine for a lovely way to wind down on a Sunday night. Call Rialto at 617.661.5050 for more information and to make reservations.
