I understand everyone's experiences can't be the same and for Hibachi Grill, my own experience seem very different from many other reviewers who rave about this place.
Yes, the owners are nice. Yes, it's interesting that they have their own sauces (like yum yum which in my opinion, didn't add much to my food experience here.)
We dined in for lunch and ordered grilled steak and grilled squid both of which came with a side of veggies, rice and soup. Good value for the money but the steak was very tough, the squid came with sprinkling of spice when I had specifically asked them to serve it plain (as it was for my toddler). They were very apologetic for the mistake and offered to cook us a new one which was a nice gesture. But even the new squid came covered in butter and we barely touched it. What I really disliked about the meal was their rice which had a weird oily sheen to it. When I asked them about it, I was told that what was served was plain rice. Umm...I'm Asian. I think I know the difference between a bowl of plain rice and rice that had something done to it. When we put the rice into the miso soup, you could see a film of oil immediately forming on the surface. Eew...
Overall, the food experience was so subpar, I never bothered going back.
