Went here during lunchhour on a Friday.
Even though it was very quiet inside (we were # 3 and 4 in the queue to actually get our food after paying), it took 10 minutes for our "fast" lunch to make an appearance. One lady was doing all the work, and barking orders at the other lady, who seemed to be new to the systems. I think that disappointed me most -- the barking of orders. All of us have been new to something, and none of us learned anything through that kind of help.
Once our food arrived, it wasn't anything to write home about. I had the spicy soup noodle bowl. It was okay ... not much flavour to it; broth was lukewarm.
In summary: I have definitely been to better japanese fast food places. I'll be looking elsewhere for lunch next time.
