If you're looking for an evening out with friends or a date, Umai is definitely the way to go. It's a bit pricier than Sake II, but the quality is definitely worth it. Another great thing is that it's BYOB so you can grab a cheap bottle of wine from Mt. Carmel and share it with friends. The decor is quaint but trendy...you almost forget for a second that you're not in Manhattan.
I actually ended up going to dinner here TWICE this weekend; that's how good it was. Both nights they gave us a free vegetable spring roll as an appetizer...The staff is incredibly friendly and grateful to have you there. We ordered a few rolls; I would recommend the Y2K roll, and the Spicy 2 in 1 Roll, although everything I tried I loved. Also, both nights I went they even gave us a FREE dessert- Oreo Tempura which is exactly what it sounds like, Oreos fried in tempura batter. They were absolutely delicious. If you haven't been to this place yet....GO!
A few people I talked to were questioning whether or not a sushi place in the Bronx could be decent, but give our neighborhood a little more credit! New places are opening up all the time and a lot of them are here to cater to Fordham students so take advantage of them. Although the Italian restaurants on Arthur are unbeatable, if you want a change of pace try Umai Sushi.
