Home to Siam Square, National Stadium, and Bangkok's central retail and cultural institutions — touristy but packed with things to do.
Pathum Wan is Bangkok's commercial center, with Siam Paragon, CentralWorld, and other massive malls — less a neighborhood, more a shopping/entertainment zone.
Multiple BTS lines converge here; the area is compact and walkable between malls.
Good hotel options near shopping; good for people who want malls and restaurants in walking distance but less authentic neighborhood feel.
