What's your opinion? I've eaten at a lot of sushi places, some that have been mentioned on this board, but I was looking to try something new (and hopefully good). Tank is a nice idea (I've eaten there, but my dining companion has not) but it's a little too pricey for a casual lunch with a friend. I keep reading about Katsu, but I think they are only open for dinner. I'm in Roscoe Villlage/Lakeview, so I'd like to stay north. Thanks!
