A luxury restaurant in Greece has hit back after a furious British holidaymaker complained online for being charged almost £300 for four drinks. The high-end DK Oyster, on the Greek island of Mykonos, is famous for its eye-watering prices and at least one guest got caught out. A woman named 'Ashley' took to TripAdvisor to share her horror of being charged €350 (£292.70) for four drinks, saying travellers should "save their euros".
