My wife and I are regulars here. We always go before 7pm to take advantage of their happy hour. I believe they have a reverse happy hour as well later in the day.
The place isn't very big, the atmosphere is that of a small intimate bistro, and they have a very nice patio area. It's the kind of place that's equally well suited for meeting up with friends or for a casual date.
The food is consistantly fresh and delicious. We've never had a bad meal here or had something we wouldn't order again. The happy hour menu has a great selection of sushi, both nigiri and maki, as well as appetizers, and of course beer and sake.
My wife doesn't like sushi. They offer a full menu of traditional Japanese soups and entrees. This place is great even for people who don't like fish.
I have two personal appetizer recommendations, the ribs are amazing as are the potato wrapped shrimp.
The happy hour pricing is fantastic. Every time I get the bill, I'm always a little shocked by how little it is for the amount of food and sake bombers we consumed. It's a great value.
