Asking questions is an important way of showing interest in peopleand learning more about them. We deployed a social robot, Coffee-Bot, capable of asking personalized conversational questions basedon topics mentioned by the user over time. We describe our evalua-tion setup and results of our pilot study. Our initial results, basedon interactions with seven participants, indicate a high level of en-joyment among participants and provided us with useful feedbackon the CoffeeBot experience for a future long-term study.
