Been going to Sakana and their many locations for years. Today the wife and I tried Sashimi for lunch. There was a buttery whitefish, it wasn't bad. I asked our waitress what it was, "buttery whitefish, also called escolar." I didn't eat anymore once I heard that, but the one piece was in and digested. Why is that pertinent? Escolar is known to cause stomach discomfort, anal leakage, and diarrhea in humans. Luckily, I haven't the leakage or diarrhea, I have been laid up in bed the rest of the day with stomach cramps. Perhaps don't serve things to customers known to the FDA and the government of Japan (they don't eat escolar) to affect the human digestive tract so poorly.
