Iku Sushi has your usual sushi rolls and take away bento boxes as well as catering for sit down meals. However, unlike other places it has a unique take on it's roll and the most famous of those is the cheeseburger sushi. This sushi is epic - it's rather large in size (definitely larger than the normal 6 piece sushi) so I recommend that you get the 4 piece (small size) rather than large, if you can barely finish the regular 6 pack sushi. I got the cheeseburger sushi with the lot. So this contained either teriyaki beef or teriyaki chicken (I got the beef), along with pieces of bacon, shitake mushroom and mozzarella cheese rolled in nori then rice then coated in bread crumbs and deep fried. It it absolutely delicious and definitely bad for your arteries. The mix of flavours is divine and it's worth the try!
