Advertisement What's the one thing you'll find in common between mega-ships, tall ships, river cruisers, expedition or boutique ships? Incredible food. Cruisers vie to set themselves apart through their culinary prowess, so food has become an exceptional element of any adventure afloat. Of all the delicious things I've been served – from fresh-baked pastries to sushi, steaks and decadent afternoon teas – the dish I was least expecting was spiders. Great big black tarantulas, deep-fried to perfection. They were the centrepiece of a 'bug buffet' providing a foray into the local street-food scene. On our journey through Cambodia and Vietnam with Emerald Cruises, I couldn't bring myself to nibble an eight-legged amuse-bouche.
