Really quiet on a weekday evening, we made a reservation but didn't need it as we were the only customers our whole stay.
I ordered the Wagyu Beef skewer (~$9), Cheese Tsukune skewer (meatball with cheese ~$3) and Yaki Onigiri (char-grilled rice ball with teriyaki sauce with kelp filling $3)
It was my first time trying wagyu beef so I didn't have a point of reference, but the beef doesn't melt in your mouth, it's still pretty chewy. It's somewhat "spongy"/ fatty because it's not overcooked, and has a slight charred taste. I don't know much about meats, but the texture and flavour is similar to tenderloin, tender and meaty. For me, the skewer was okay, I don't think I'll pay again for it, I didn't find it much different than your other cuts of beef.
The meatball and yaki were both super greasy! The cheese in the meatball was some sort of aged cheese so it has a bite to it. The rice was in an odd oblong shape, not triangular, and the texture is quite sticky. There wasn't much flavour inside, despite the kelp filling.
I'm not impressed with the greasiness of the dishes. I recommend going downstairs to the 1st floor and getting Ramen instead or go to Manpuku for better yaki
On the plus side, great service and friendly staff.
