This restaurant is truly a hidden gem in Pittsburgh.
And by hidden gem, it is pretty hidden and hard to find (but also delicious and unique!). Just a red glowing sign with just japanese characters on the outside, it looks like a residence. Then you're faced with two nondescript wood doors, like a choose your adventure game. You then trek up two flights of narrow stairs into a completely different world. The ambiance is super cool, with the lowered tables.
My friend raved about the robotayaki, but I found it to be slightly underwhelming. On the other hand, the Takoyaki (octopus balls) and the Nasu Shigiyaki (eggplant) were phenomenal. I also ordered the matcha slushee and it was one of the prettiest drinks I've ever seen. My friends got the chirashi bowl and found it to be good, but pricey for the portion size and they left hungry.
