Ate here this past weekend with the Groupon deal. The deal has good value for the amount of food you get. We had the sashimi appetizer and the starter salad which resembled a bento box offering with the carrot ginger sauce. The chicken karaage was not the most flavourful, but also not bad. For mains we had the chicken and steak which came with a fun show from the chef. We were lucky enough to have been tossed a few shrimps from someone else at our table, and those were very tasty, I wish I had ordered it instead! Definitely worth the upgrade. I like the idea of a hibachi steakhouse, but maybe my palate would have been more satisfied ordering off the main menu.
Overall, we had a fun experience here trying somewhere new, but if it weren't for the Groupon to lower the price I don't think that we would return. Benihana should really revamp the space, and maybe dim the lighting a bit so it doesn't have such a cafeteria feel.
