There are different styles of music in various lounges around the ship starting about 4:30 PM Each set is usually 45 min. and then musicians rotate between venues. Usually a classic string duo or trio, folk type solo guitar, larger group such as jazz group, big band, etc. The "house band" will be mostly playing in the atrium and will be pop and rock music. There is usually an Abba tribute one night. Sometimes, the Tuscan Grill and/or Murano will have one less expensive lunch, but not on every cruise. Sushi on 5 has great Japanese food, with plenty besides just sushi, at very reasonable ala carte prices. Google for a menu. Also check out the Spa Cafe for breakfast and lunch. It is NOT just for spa patrons. Lite and tasty dishes. I love their salads. No charge at Spa Cafe. The Mast Grill serves very tasty burgers and fries as well as hot dogs at no charge every day from 11 Am to 6 PM. Some hours may vary
