This place is amazing.
I've recently started making poke bowls at home and this place is amazing for getting sashimi grade fish. I've gotten salmon, albacore tuna and skip jack tuna and it's all delicious and reasonably priced. Blue fin tuna comes from Tsukiji fish market and it priced accordingly - but they have it, along with other essential Japanese seafood items such as bbq eel.
As long as the store is not full, they're genuinely happy to have even a lengthy conversation about what you're looking for and educate and make recommendations. I simply love this place and the service is second to none. I bought a sashimi knife and I was told I can bring it back anytime to get it sharpened, free of charge. It's rare to get this level of customer service anywhere.
