The Steakhouse Restaurant is open between 19.00 and 22.00 and costs £14.95 per person or £34.90 for 2 inc a bottle of house wine of the day (usually quite nice). The Oasis Restaurant has the same opening times and has a wider range of menu and costs £12.50 per person or £29.90 for 2 inc a bottle of house wine. Both restaurants come highly recommended and you need to book in advance. Smart casual attire is required in both.
Hope you are going soon as RCI are taking back Island Star in March 09 and all cruises therafter are cancelled.
