We went for the teppanyaki supper (family of 5) and ordered chicken, steak, salmon and sukiyaki. The steak and fried rice was really tasty. The sukiyaki didn't taste like "sukiyaki", more like not very flavourful bulgoki. The decor was modern and the chef liked to (practice) juggling his spatula and fork (the fork landed on the floor, good thing it was a knife).
I went with a Groupon voucher ($35 for $70 worth) and when it was time to pay the waiter informed me with this deal, he will add 15% gratuity on the bill. I would gladly do it if I had good service from them (2 waiters taking an order from my daughter who asked for a glass of water and they forgot to bring it). They did not inform me the fried rice is an extra $2.95 each (most wait staff will inform customers of that). I reread the voucher and it didn't. Mention about the mandatory 15% tip. I brought him the print out and he read it over and over for a long time and said he always adds the tip on. Then he points to the section that says gratuity and taxes not included. I said that doesn't mention the 15%. He had to add, "oh, I won't add it this time". I replied yes because if you did you would be dishonest.
I don't believe I will be going there again for teppanyaki as I thought it was a bit pricey. After the $70 credit I paid an additional $57 (including tips).
