text: Yes it's pricing information for the tourist attraction, and a list of bus routes that can reach it. Same user added a few such notes over Dublin, including this one where (s)he is logge in: http://www.openstreetmap.org/note/673925
  
  I feel that prices are out of OSM scope due to maintainability, but it doesn't stop people from trying (http://taginfo.openstreetmap.org/search?q=price). I definitely wouldn't add them myself but I find it hard to say "thou shall not tag prices in OSM" and close this note.
  
  OTOH, it'd be worth checking that all the mentioned bus stops are mapped.
