i thought blue lagoon beach day was a fabulous excursion in aug1999 when we went on the 4day cruise. the food was aweful but i still wouldn't head back to the ship to eat. don't waste any of the few valuable hours you have on blue lagoon by going back to the boat to eat. the kids food was better than the adults. either way, it is edible, just poor quality. try taking a bagel, fruit or something that won't spoil from breakfast and eating it on the island if you don't like the lunch. but stay as long as you can, it's a beautiful place! then pig-out when you get back on the boat!
