I've eaten at Rodney's a few times, and am quite a fan. In terms of oysters I usually just ask the people at the counter what is good that day, and I have never been lead astray. They know what is best/freshest. I always order teh manhattan clam chowder as well. As someone who is lactose intolerant it's great to have a non-dairy soup option. I recommend sitting at the oyster bar. I almost always do, and I have always received great service. Once I was even sitting next to the owner! Plus I enjoy watching the shuckers work.
