As a biologist I know the risks but, I know that are ways to reduce the risk and also raw fish is delicious
I love sushi raw fish ahha. For sure, safe bet is to go to a place that knows how to properly handle and prepare raw fish.
This all you can eat seems kind of garbage xD. I think they tried to be too universal and then didn't become good at anything. The rice with the raw fish makes sense. The rice will make you full so they can save money.
I think you could find places with that price range and be better? I'm not sure what it's like there though D:. I see it as like it's ok going once to try but then it's not good enough to go back again :P at least that's the vibe I'm getting reading your post.
