The Park Cafe replaced the original Solarium grill which always had pizza, burgers straight off the grill (the cheese was melted), and hot dogs. I'm not sure why they kicked pizza to the curb on Grandeur. In many ways I think they should have left things alone and not installed a Park Cafe. I guess I am in a minority but I am not at all impressed by the Park Cafe on the Oasis/Allure, which is where the concept started. It's a confused mess at times with no clearly laid out service lanes for the stations. I also found the roast beef sandwiches to be so-so. But to each his own.
On the newer ships, Sorrento's Pizza is a stand alone place with pizza, salad, antipasto. I had a great antipasto plate one day on Liberty Of The Seas last December.
