I've been here quite a few times and it's one of my favorite sushi places. Warning, it's hard to find parking and inside it can be packed, so don't be surprised if you have to wait a while for seating.
The bento box with Mark's Roll is my order to go to. This is one of my favorite sushi that is exclusively from Cowfish. As a side note, you can mix the side dishes in the bento box if you don't want the given sides. Definitely, a place you would not want to miss!
