Sun’s out and the buns are coming out with the return of the Sycamore burger. Every Wednesday, you can sink your teeth into a juicy meat patty, covered with Cabot cheddar, black pepper aioli, bacon and lettuce on one of A&J King Artisan Bakers’ sesame brioche bun. Served with a side of homemade fries and ketchup — it’s happiness on a plate. Chef-owner David Punch and the pack only make a limited amount each day, so make sure to reserve a spot early on their patio or order online before they sell out. Some say it’s the best burger that they’ve ever had, head to Newton to taste for yourself.
