Don't use that fork! We found a kid-friendly chopstick cheat that actually works. Matsu Sushi in Westport has done away with the rubber bands and balled up paper technique in favor of this ingenious little add on that snaps into regular chopsticks.
Chopsticks aren't the only reason to go to Matsu. The sushi is as fresh as any I've had in Fairfield County, and the staff always seems positively delighted to see me roll in with my posse of three kids. It is the perfect 5PM family dinner when you just don't feel like cooking. They even deliver!
