The tramcar itself was awesome, service was excellent and the scenery was beautiful. The only thing keeping me from giving this five stars is the food. The food for the most part was good, however, the kangaroo loin and steaks were definitely overcooked - well done really no matter how you ordered them. That's minor though because you're really going for the experience which was wonderful!
I hate to give this only a two, but having done other city tours, this one was really just so-so. The guide was really nice and showed us great things, but it was bogged down with a lot of information that's really not that relevant to seeing the sites. Also, it would have been nice to have slightly longern in the places you stop which are only two - Fitzroy Gardens and the Botanical Gardens. Beautiful city though!
