I just went to Yamato for dinner. I have been to a few tepenyaki restaurants so I like to think I have a good comparison. There was 1/5 chefs that really put his heart/effort into providing an entertaining dining experience. My server was friendly but didn't really do any tricks aside from the standard onion volcano. I ordered the beef roll... Do yourself a favor and order something else. I personally expected way more from it based on location(prime yorkville), price and reviews.
