Now that you've had your local specialty lunch, follow Chai Khong Road to its western end for dessert. On tiny Soi 0, not far from the river, locals have been crafting sticky rice in bamboo, or khao lam, for decades. After being slightly sweetened with a touch coconut milk, the glutinous rice is stuffed into wide shafts of bamboo and grilled over a charcoal fire. The snack was once favoured by soldiers due to its ease of transport and ability to last for long periods without spoiling. The char-grilled treat is sold throughout the day, but you'll need to get here in the early morning to watch it being prepared.
