This summer, it will be easier to get a table at Chestnut in Carroll Gardens. The restaurant is expanding into a separate bar space next door, says owner Daniel Eardley. Look for a bar menu featuring small plates and a selection of handmade chocolates. In the bar, you’ll be able to order from Chestnut’s full dinner menu, but that option is not reciprocated in the dining room. “We’re keeping Chestnut open for business during the construction next door, but expect to see a short closure at some point and reopening in the next six to eight weeks,” Eardley says.
