I've always wanted to try Yamato since I always pass by it. Having recently had an exceptional teppanyaki experience in Mongolia (odd place to have Japanese food!), I was determined to give it a try.
I ordered a "Daimyo" with fried rice (+$5), which included ribeye, lobster, scallops and veggies.
The chef/cook was a pleasant Japanese man, joking around with all of the customers around the grill. There was a lot of showmanship involved while he worked the grill: spinning and cracking eggs, lighting various things on fire, tossing and banging random objects at hand... It wasn't exactly my thing, but I didn't mind it either.
The food didn't come out amazing, it lacked the intricacies that made Japanese food world-renown. Most items came out charred, and tasted burnt; the quality of the ingredients were average at best, and the seasoning was very one dimensional.
I probably wouldn't go back for a long while.
