Ichiriki is a NICE restaurant, suitable for a date night with Yorkville prices to impress $$$. Quite authentic, the head itamae is Japanese and they have jazz nights as well.
The food itself is quite par, with expensive ingredients (triple A striploin for beef teriyaki) that don't really justify or hitting the market target. So the prices I find exuberant. The restaurant also closes extremely early (9 PM).
What is really noteworthy are the desserts. Strong mango pudding and green tea pudding game but I also heard the puffs were amazing. Guess what, you can get takeout dessert too!
I recommend a try but return for the desserts!
