I've been to the store listed below several times. Although I don't know what you're looking for specifically but the quality of fish is excellent. I don't mind paying a few extra bucks for good quality seafood, especially when it comes to sashimi. A mutual friend of mine and her family own this place. Give them a call for their prices.
If you're looking for quantity, go up to Samurai Sushi and ask to buy a slab of salmon from them?
