"This one's an institution. You'll find a line forming as the stall begins to set-up and a real snaking queue when it actually opens for service. Cai Chuan Tou Mutton Soup has been operating from Bukit Merah View Hawker Centre for over 30 years and has amassed quite a following during the only service it is opened for: lunch. It's prepared in the rich, herbal Teochew style but with a real peppery kick. And the best part is that the soup is refillable. So bottoms up!" - Alethea Tan
