I'm sporadically regular customer of Umi Sushi for years. The restaurant is still the best sushi joint on Nun's Island although relatively pricey. It is also a little cozy place with real table cloths and small sushi bar, where you can wait to pick your take away. There is a nice fish selection in the sushi list, variety of rolls and fresh sashimi you can fill your sushi boat with. The menu has also a good choice of dishes. The service has been always very attentive. My last visit was on Friday night and the personnel was definitely overwhelmed with the amount of people they need to take care of, two people were struggling to run in between the tables to take care of the customers orders.
