S1	1	Welcome to our shop. Is it correct that the reason for your visit is to decide on a travel destination?
C1		Yes, that is correct. I am here to decide where to travel.
S2		Yes, I understand. I would like to ask you a few questions. Which of your trips to Osaka was the most memorable for you?
C2		Yes, the trip to Osaka was memorable.
S3		Osaka…. It is a very nice spot. You must have many memories from that trip, such as the food, scenery, etc. What would you say was the most memorable?
C3	2	Yes, I had many memories from my trip to Osaka, but my most memorable memory was going to USJ and playing there.
S4		USJ in Osaka is very famous …. I think it is a very good memory …. Did you buy any sweets as souvenirs on your trip? Is it a sweet candy?
C4		Yes, I bought some snow cones as a souvenir.
S5		I see … You must have bought at least one type of sweet snack as a souvenir…. Are you the type of person who sets aside a large budget for your trips?
C5		No, I try to keep my travel budget as low as possible.
S6		That’s right …. You want to enjoy your trip inexpensively, do not you?
S7	3	Excuse me …. I’m sorry, I’ve rambled on a bit too long. Actually, I am guiding you with a character that fits your needs based on the information I have obtained from you. Today, I, Erica, your travel guide avatar, will be in charge of you.
S8	4	Let’s decide on your travel destination. I would like to narrow it down to Chinese spots that I think would be suitable for you.
C6	5	I like the idea of narrowing it down from Chinese spots. I agree with that proposal.
S9		Yes, sir. The destinations that we are handling as Chinese spots are Tokyo, Hokkaido, and Osaka. Assuming that we do not compromise on budget, I would like to recommend Hokkaido.
C7	6	Thank you for recommending Hokkaido. Hokkaido is also an attractive destination. We will choose Hokkaido.
S10		Yes, I understand. This time, I would like to recommend Takahashi Manju-ya in Hokkaido to our customers. It is one of our most popular places to eat meat buns and cheese oval pancakes. What do you think?
C8	7	The Takahashi manjyu shop in Hokkaido is very attractive. The meat buns and cheese oobanyaki look delicious. I will try to visit that spot.
S11		Thank you …. The other reason why I recommended Hokkaido is because I would like you to buy Jaga Pokkuru as a souvenir. It is a popular product in Hokkaido. Thank you for visiting us today. We look forward to serving you again.
