This is our "go to" restaurant, all year 'round. Yoshi offers a great selection of very fresh seafood. In addition to Sushi, there is tempura, Japanese fusion entrees, great salads, appetizers and soups. You can't go wrong. This summer a bar will be added in addition to BYOB. The wait staff is super and the atmosphere relaxed.
Spent a night over on the island and were looking for something for dinner. Couldn't decide - had been on a business trip in Boston and were used to eating big every night on the expense account. Nantucket is definitely a target-rich environment if you're looking for a fine-dining experience, but after a week or so of that, we had a little bit of restaurant fatigue. So in looking at number of restaurants and menus in town on the island we weren't seeing much that appealed to us - all big, heavy, formal dining type spots. Walked by a cross street and the wife saw the sign for Sushi by Yoshi, and something cool and fresh sounded perfect. This place was the perfect antidote for formal dining fatigue; just a little place with very few tables inside and a very plain interior. We unfortunately dined at the same time as a VERY loud and rowdy crew of folks, and were glad when they left and the wife and I could talk to each other without shouting or listening to the ear-splitting laughter and anecdote-telling of that one table. Sushi was very good - the only concern here was that the nori seemed a little chewy and maybe not freshly toasted. Also, be warned - this place is BYOB, which is nice in some ways, but will involve a separate run out to the liquor store about 3 blocks away (which is a very reasonably priced spot, though the selection of single beers isn't exactly stellar). Come prepared.
Our family has lived in Tokyo for 6 years, and my wife is Japanese, so we came to Sushi by Yoshi for a familiar meal. The menu offers a greater variety of real Japanese cuisine than many sushi shops: Tokyo-style ramen, curry-rice, udon and soba dishes, as well as a nice assortment of sushi (maki and nigiri). The sushi chef recommended the caterpillar roll, with soft avocado covering the outside of the roll, and it was delicious. The service was quite friendly and efficient. You may have to wait for a seat - there are only 22 spots, and we waited for about 30 minutes at 7 p.m. on a Saturday. The meal was well worth the wait!
