Tenichi was the first all you can eat restaurant that I ever went to, nearly 20 years ago. As far as I know, they've changed a lot since the last time I came (which was about 5 years ago). Unfortunately, it's not as good as I remember.
Things to note:
The saba sashimi was watery. I bit into it and got a mouthful of water.
The escargot was dry and had no flavour.
The avocado seafood salad was bland.
The chicken skewer was dry and overly salty.
The takoyaki was mushy.
The dessert was mostly good. The tiramisu, custard, papaya soup, chocolate mousse.
The ginger milk needed a little more ginger. The mango yogurt, which I swear was invented by Tenichi, was slightly hard and lacked its unique flavour.
The aburi sushi was great. I especially enjoyed the scallop and salmon.
For the most part, it was decent for an all you can eat restaurant though disappointing due to our expectations from previous visits.
