I always order here and just completed ordering 4 All-in sushi platters (56 pc). It was an urgent request and they made it possible on time. Their attitude and service is great. I have no idea of some of the customers leaving here with bad experience.
(Update) The team here at Yummy also gave me some service (free of charge) rangoons, egg rolls, and etc., for ordering all these platters for an event.
I have also ate here several times and loved the restaurant. I would definitely ask people to give it a try and judge for themselves.
