Thai food varies from region to region due to geography and history. In the West, most Thai restaurants serve Bangkok-style cuisine, so travelling in Thailand is a culinary adventure of discovery. Lanna-style cuisine comes from the mountainous area of the country, where the winter months are much cooler then anywhere else in Thailand, with some regions even reaching freezing temperatures on the mountain tops! The region is abundant with wild mushrooms, forest vegetables and fruits and wildlife which all feature in this less well-known regional cuisine of Thailand.
