Eating a meal in complete darkness is guaranteed to heighten your sense of taste. This is dinner at Dine in the Dark, a restaurant at the Sheraton Grande Sukhumvit where the waitstaff is made up of visually impaired people. For every delectable meal purchased, the hotel makes a donation to Thailand's Foundation for the Blind. Dinner is a four-course set meal—choose vegetarian, Western, Asian or the surprise menu. Open for dinner only.
