This review is for the Beach as a place to see bands in the evening, not for swimming/sunbathing.
My mom and I went to see the Go-Go's...it was an awesome place to see a band! They play on a stage in the water and you can either stand out in the calf deep water or sit on the sand or on a concrete ledge. The place holds a lot of people and there was plenty of places from which to get a good view. It was a super enjoyable place to relax and see a concert.
The sound system is surprisingly strong enough to overcome the sound of the artificial waves and the planes overhead. The Go-Go's were great and it looks like the summer lineup will have other good bands. The ticket prices were very reasonable too, less than $30 which apparently was a good deal since the Go-Go's were going to play San Francisco for like $50 a ticket.
