My husband and I are booked on the September 21 cruise on Zaandam - Vancouver to Hawaii - and we would like to try the Pinnacle Grill. Does anyone out there know what the dress code is on a sea day at the Grill. We are interested in dinner and lunch dress codes. Would a golf shirt and dockers be all right or is a jacket and tie required. Would appreciate any feedback. Also can you make lunch reservations online or do you have to wait to be onboard? What do they usually offer for lunch? Thanks for the info.
