During normal daytime business hours, Bento serves asian cuisine including fresh Sushi and many " bowl" entrees such as teriyaki rice bowls or noodle bowls. Honestly, the Sushi is not half bad but some of the bowls and other entrees are less than palatable. Unfortunately, the chicken is not that good and the sauce is tasteless. The rice has a weird, consistency. It is sticky, which I like, but tastes a little over-cooked. Honestly, there are better (and cheaper) asian restaurants nearby.
The reason I gave it 4 stars. After 7pm, the bar on the upstairs level opens. It is a very hip and chill atmosphere. The bar tender is very cool and makes an excellent dirty martini. The real treat is that they are one of the few places I know of that serves Saki - you just cant get enough! They have a DJ booth and feature mostly house and other electronica DJs - one of the more appealing parts of the bar.
All in all, avoid the food but not the bar.
