We did the mystery dinner at Portofino on Adventure in February. It was originally scheduled for the first formal night (second evening of the cruise) but was changed to the third evening. I'm not sure if Adventure usually holds it on the second or third evening. The price was $49.50 per person.
It's something different and worth doing once. The acting was way over-the-top and very silly. It's definitely not a Broadway production but it was fun. The food was not up to Portofino's usual standards because they do serve everyone at once. My shrimp was dried out like it had been sitting under a heat lamp for a while before being served.
We started the evening in the Viking Lounge with sparkling wine and some toast hors d'oueves. The actors gave a set-up for the mystery. We were then divided into 6 groups of around 16 people each and escorted to Portofino.
Once in Portofino, we were given a choice of red or white wine. If you don't drink wine, they will bring sodas or tea. The wine was unlimited. The appetizer was a choice of either ceasar salad or soup of the day. Our soup choice was creamy mushroom but that can vary. They also brought out a variety of breads. After the appetizer, the actors provided some more background on the mystery. Our entree choices were beef tenderloin or tiger shrimp. After the entree, each table was allowed to pick one actor to ask a question to help solve the mystery. Everyone wrote down their choice for the murderer. Then everyone got tiramisu for dessert, which was really good. After dessert, the mystery was revealed. The people who selected the correct murderer were put in a drawing to win a gift basket.
I enjoyed the mystery dinner once, but don't think that I would want to do it again for a while. The menu was very limited and the quality not up to Portofino's usual standards. We went back to Portofino later in the cruise to experience the full menu and had a wonderful meal.
