My wife and I took an Argosy dinner cruise with our company about a month ago. Generally we had a good time. The cruise provided wonderful views of Seattle, especially at night, and took us through several little island nooks that were fun to cruise by.
I'd say the food was above average for a dinner cruise - a reasonable selection and pretty well prepared. The desserts were quite good.
There were two things I didn't like about the cruise. First and foremost, the band had a very louge act kind of feel and was not much fun to listen to. They should have been playing jazz, not more contemporary fare that doesn't exactly suit people having dinner conversation. Second, there was way too much upselling on the cruise. There were so many rules about what was included and what was extra it got annoying.
Overall we had a good time but once was enough, at least for this particular cruise.
