While it seems a little quirky, this is definitely worth a visit for the Camera Obscura at least. Be sure to go when the weather is good (clear, sunny) as otherwise, your experience of the Camera Obscura will be diminished. The other floors can get very crowded so be prepared to deal with that. Alternatively, you are allowed to come and go as you please throughout the day so you can come back when it's less crowded.
