On top of the sliders, I also ordered the Spicy Mayo Char Siew HH Sushi ($5) and the Spicy Salmon HH Sushi ($5). It's on promotion if you reach there before 7pm. I would say that both sushi were done well but I'm still a greater fan of cold raw sushi.
The brother had his sights on the Sashimi Mazemen ($22) which is a combination of assorted sashimi and cold noodles. His assessment was that the raw fishes were really delicious with the slices very thick and generous. He also took notice that despite its thickness, the fishes were very easy to eat. The cold noodles and onsen egg that comes with the bowl play the role of the side dish to provide a complete meal experience.
Being at the bar, it'll be a waste not to try some of their sakes and my brother ordered the passion fruit sake ($10) to go with his meal.
I would say that Sumo Bar Happy is a pretty interesting concept which appeals more to foreigners used to bar top dining. I found the experience cramp. The menu selection has a number of unique dishes however there's an over emphasis on beef. As someone who doesn't eat beef, selecting a spread is rather challenging. If beef, alcohol and Japan agrees with you though, you might wish to check this place out.
