Nobody seems to know if Davis Square's Rosebud Diner is closing or not. We called this morning and spoke with a longtime employee who told us this: "You know what, honey? I've been here for 15 years, and you're the third person to call us this morning. I'll tell you what I tell everyone: We're still open as of now." For her sake, if a new restaurant does take Rosebud's place, we hope they snap her right up.
