Sumo is your slightly above average AYCE sushi restaurant.
Tip: They take 10% off if you pay in cash.
Sumo was pretty empty on a Tuesday night that I came in.
The restaurant was bright and seemed very clean. They also have the iPad ordering system.
Food here is very average. Sumo tries to be creative and add items to their menu that other restaurants wouldn't but ... for example, they have "spicy" miso soup - which is literally miso soup + sriracha.
Their torched sushi was very, very, very average and did not add to my dinner.
The best part was their sweet shrimp - this usually comes out on weekends in other restaurants; so having it on a weekday was a bonus.
They do have scallops and octupus which are restricted for the weekends.
Their teppanyaki and cooked section was good but nothing that tops other restaurants.
Do try their sumo rolls - it looks weird but does taste good.
$28 for a average week-day meal.
I won't be back for a while just because I want to try others AYCE but I won't complain if I get dragged here with friends.
