Generally impolite, but toleratedMedium confidence
Explanation
In Thailand, slurping noodles is not considered polite as it goes against the local custom of eating quietly and with restraint. While it may be overlooked in casual street food settings, especially with tourists, it is generally seen as lacking manners in more formal dining environments.
Varies locally: In northern Thailand (e.g., Chiang Mai), some locals may be slightly more tolerant of slurping due to influences from neighboring Laos and Myanmar, but it remains uncommon.
Local Tip
Eat noodles quietly by using your spoon and fork to twirl the noodles, and avoid making loud slurping sounds to show respect for Thai dining etiquette.
