I can't remember when I've actually spit out my food because it was so bad, but that's what happened to me with Sushi Roku's tofu. I had ordered their "premium homemade tofu" three ways (truffles, caviar and lemon oil, scallions and sesame oil). The tofu had this sourness that concerned me about its freshness...and then I literally spit out the truffle tofu because it had a rotten taste to it! Bleh!!
I wasn't expecting great Japanese food in Phoenix, but I thought Sushi Roku would be a good bet since it's part of a group that has restaurants in SoCal and Vegas. Wrong bet.
The king crab miso soup tasted like the instant miso soup you buy at the grocery store with old frozen crab stuck in it. Ironically, I had thought it'd be safer to minimize the sushi since I'm surrounded by desert, but the spicy scallop roll was the one item that was actually wasn't bad - nice chunks of scallops that weren't overly sauced.
I've had decent sushi/Japanese food in Phoenix before...but it was definitely not at Sushi Roku. To add insult to injury, they charge high prices for the bad food and slow service. Thank goodness I didn't get sick after eating that tofu!
