I've heard lots of hype about this place, then heard negative comments about the service and so just kinda pushed it on the side of my list for a later time.
It is right next to my work now so a couple of weeks ago when it was really sunny, my colleagues and I decided we'd go have lunch outside. As Kinka was completely full on the terrace, we popped over to Kampai instead. It was almost empty, with maybe 2-3 tablea occupied. So I figured we were in for it....
To my surprise, the food was actually quite good, service was nice because there was pretty much no one (lol!!). It is a little higher priced than other Japanese restaurants around but the quality felt better and we were quite happy with what we got: Grilled hot bowl and Poke bowl.
I'd come back again for a sunny lunch on the terrace :)
