We've always liked this place, even though I thought they were crazy with a burger/sushi restaurant concept at first. But it works! The food is good, the menu has something for everyone, the portions are large (for those who like that) and the flavors are generally very good. We've been hooked on the bento boxes and tend to get those as we can't make up our minds for a single item. The bento boxes include a slider, sushi, Asian cucumber salad, edamame and sweet potato or regular fries. My only criticism is that the sushi chefs sometimes lack the necessary fish cutting skills and cut the fish too thickly (sorry, but in the case of sushi, bigger is not better). But Cowfish is a solid choice with consistent quality.
The large rear patio is also a great dining option.
