The food in Phonsavan is greatly influenced by the diverse ethnic groups that inhabit the region, such as the Hmong, Tai Dam, Khmu, and Tai Phuan. Their culinary traditions combine with Laotian staples to create a unique local fare. The area is particularly known for its use of fresh herbs, foraged ingredients from the surrounding hills, and an emphasis on sticky rice as a staple. Due to its location in the Xiangkhouang Province, which experienced significant historical upheaval during the Secret War, the food also reflects resilience and adaptation, integrating influences from various cultures including Vietnamese and Chinese cuisine, particularly in noodle dishes and broths.
Phonsavan offers an interesting mix of Lao mountain food alongside international options. While vegetarian dishes are available, many local specialties tend to feature non-vegetarian ingredients, so it's advisable for vegetarians to communicate clearly when ordering.
