Speaker	Utterance
S	Welcome. Oh, those glasses you are wearing today are very nice. Are they your favorite?
C	Yes, they are my favorite.
S	I see… I just had to ask you this question because you looked so good! I’ll start the travel guide. In fact, I will guide you with a character tailored to you based on the information I obtained from you. Today, I, the travel guide robot I, will deliver you a loud, clear voice and lots of smiles. Today, I will introduce you to these two spots and suggest the recommended spot. Well, referring to my large database, I introduce the Tokyo Trick Art Museum, where you can enjoy hands-on art using optical illusions. Sounds interesting. The Tokyo Metropolitan Water Science Museum is a hands-on museum that introduces the wonders and importance of water from a scientific perspective and deepens interest in water and waterworks. This one is nice, too. Now, I would like to ask you a few questions so that I can recommend a spot! First, What past trips do you remember?
C	Germany.
S	Germany sounds great! So, what do you remember about Germany?
C	I remember seeing castles, eating meals, and riding the train.
S	I wonder what German castles look like. Who would you like to go on the trip with?
C	I want to go with friends.
S	So, you are traveling with friends. Let’s think of a good trip! Hmmm … Thanks for telling me.
S	Based on the trends I have heard so far, I recommend the Tokyo Trick Art Museum. As shown in this photo, this spot is filled with various surprises, such as paintings that appear three-dimensional, artworks that change impressions depending on the angle from which they are viewed, and rooms that allow visitors to experience optical illusions once inside and are recommended for outing with friends. By the way, just to confirm based on what I’ve heard from your memories, I guessed that you place more importance on having a good meal at a restaurant around the spot than on enjoying the spot’s facilities more deeply. Do you want to emphasize this on this trip as well?
C	Yes.
S	Hmmm…I guess that’s what you want to focus on, is not it? If so, I would recommend a nearby restaurant called “Ocean Club Buffet DECKS Tokyo Beach”. This restaurant is a buffet restaurant where you can enjoy your meal. Please let me know what you think next time you visit the restaurant. My database will grow and I will be able to make a more personalized offer to you. Now that I have explained why I recommend Tokyo Trick Art Museum, does this introduction make you want to visit this spot?
C	Yes, I would like to visit there.
S	Yay! I’m glad I was able to convey the charm of this spot to you. So, do you have any questions about Tokyo Trick Art Museum, such as fees or the parking area?
C	How much are the fees?
S	High school students and older are 1,000 yen, 4 years old to junior high school students are 700 yen, and children under 3 years old are free. Do you have any questions?
C	Where is the nearest station?
S	It is a 2-minute walk from Odaiba Marine Park Station on the Yurikamome Line or a 3-minute drive from Daiba Gateway on the Metropolitan Expressway. I’m sorry to have to say goodbye to you now because my power is about to go out, so this is the end of my travel guide. Today, I proposed a trip with your friends to the Tokyo Trick Art Museum and then to Ocean Club Buffet at DECKS Tokyo Beach when you get hungry. I wish you a wonderful trip. Thank you very much for visiting here.
