Something different that I recently tried was korean style halibut sashimi. This restaurant has tanks of live halibut and abalone. The chef takes one out of the tank after you order and filets it up. The texture is quite different than japanese sashimi. it's more firm, and you eat it like a lettuce wrap with garlic, jalapeno, this type of soy bean sauce, vinegar, and whatever else you want to put in it. It was actually pretty good. You get a ton of side dishes with it too.
medium live fish: more than enough for our party of three | Yelp
