My brother and I decided to give this place a visit after all the rave reviews, and it's definitely a nice place but small and busy - you defnitely need reservations. We were heartbroken when they told us they were completely booked up for dinner on a weeknight (what!), so we decided to get take out. Then we were heartbroken even more to find out that we couldn't order any sushi, since the sushi chef was completely tied up with all the sit down orders. Le sigh.
We ordered the gyudon and a chicken katsu curry meal to go, complete with the green tea cake and the bailey's cake. The cakes are fantastic, and completely worth it. The cooked food is good, but nothing amazing. I know I know, I need to come back to try the sushi. It's on my to-do list while I'm in town.
The staff is friendly, but they seemed pretty stressed out with all the orders coming in. It's hidden away in a side plaza, so you'll need sharp eyes to find it - they don't have an "open" sign out front or anything and it's sort of dimly lit, so it always looks closed from far away.
