I went to the Pearl (Perlan) strictly for the observation deck. (I didn't go in the Saga Museum, eat at the restaurant or hit up their cafeteria. I did look at their souvenirs but was not impressed.)
The observation deck is free. (Just take the elevator up. Go through the revolving doors. Prepare to be enchanted by the view.)
The views are amazing! You get a 360 degree view of Reykjavik. Definitely worth the walk or drive!
