You look around, trying to find the "Princess Daisy" that Peach wanted you to meet, but as you glance to your right, you see...a princess, in a yellow-orange dress, sitting in the tavern. She doesn't look very happy, and there are two empty glasses next to her on the counter.

She does have the Flower Kingdom pendant on her chest, though. Maybe this is Princess Daisy? You slowly walk into the tavern to look.
