Grab a guest pass and head to Thammasat University’s main library, the place to be if you need to do some research on Thai political history or are hunting down a quiet place to read. The multi-level subterranean library has an impressive catalog o books, study desks, and open spaces. It’s also one of the very few (if only) libraries in Bangkok that allows you to bring in food, but under one condition: nothing that will stink up the place.
Entry is priced at B20 (free for Thammasat alumni) and annual membership costs B500 per adult.
