Just discovered this out-of-the-way, hidden gem in my work hood.
And have been mildly obsessed ever since.
Located just inside the doors of 75 Sherbourne, this sushi bar (errr....more of a take-out stand) has super fresh, super delicious rolls and sushi. Items come pre-packed in take-out containers, but don't let this scare you off, its delicious.
My go-to order is a mixed box of sushi (today's included two pieces of salmon sushi, one shrimp, one yellowtail and one tuna) and 6 pieces of their dynamite roll. The rice is perfectly cooked, not too sticky, not too warm, just cooked enough to hold its shape and stick together. Its the best rice I've had with take-out sushi in the city. Fish is all super fresh, not fishy-tasting at all. Also have had their wakame salad and their miso, both were good. not amazing.
Prices: Not the cheapest take out, but also not super expensive. My order with a miso soup was $12. I'd rather pay a bit more for great quality than eat the crap they sell at the local grocery store.
