I have been to Cowfish a couple of times. I love the modern atmosphere, and although there is almost always a wait for the table, I appreciate the fact that the bar offers the full menu. So if it is just you and a couple of people you will most likely get lucky by catching seats at the bar.
The Sushi is okay. The flavor is good, however you don't get that taste of freshness that I always love when eating sushi.
The burgers are good! I am not a very adventurous person when it comes to my burgers, but I enjoyed reading the descriptions of all the different and odd burgers they offered there. I got the BBQ burger and it was very good. (Better than the sushi in my opinion)
The drinks are excellent! I always end up getting the spiked milkshake, it is absolutely delicious for anyone with a sweet tooth.
Service is average. However, it should be better for the amount of money that you pay to eat there.
I have seen a few families with small children there. In my opinion this is not much of a family atmosphere. However, some people obviously disagree with me. I just find the food and the overall ambiance a little too mature for children.
