Excellent! Came at around 9.30PM on a Sunday evening, queued for about 20 minutes. By the time we left around 10.30, there were no more queues. They have a huge variety here for 100 yen, and lots of special seasonal dishes too. Notes:

• They have amaebi (sweet small prawn) for 100 yen
• The seafood steamed egg for 180 yen is super delicious and fresh and full of seafood, definitely order this. It had crab, small scallop, and some sort of sea snail or shellfish. Tried to order another one a few minutes later, and they were sold out
• They have uni (sea urchin) for about 220, but it was sold out when we got there
• Snow crab was also on the menu, but sold out
• The eel wasn't very good, would not recommend. It's not teriyaki eel, but possibly steamed - the texture is a bit powdery.
• Hokkaido scallop was great, and super fresh
• Try the shirako (cod fish sperm sacs) if you've never tried it before. It's quite mild and creamy, and not very fishy at all! Beside the shirako, it came with a quite sour orange coloured jam, so you might want to remove some of that jam as it's very overpowering.
• Note that all the sushi is made fresh to order, you won't find any plates circling around and around on the belt like a sushi train. Everything must be ordered off the tablet.
• If you don't want to eat Japanese food for some reason, you can be a total tourist and order coke, fries, and fried chicken here too.

Overall highly recommended!
