Great question! Both have their unique vibes:
Bangkok: Classier nightlife with rooftop bars, nightclubs, and red-light streets like Soi Cowboy/Nana Plaza. More variety — you can combine nightlife with shopping & temples.
Pattaya Walking Street: More wild, chaotic, and famous for neon clubs, adult shows, and beachside nightlife. Music, dance, and entertainment run till morning.
👉 If you want balance (temples, shopping, nightlife): Choose Bangkok.
👉 If you want full party mode (bars, nightclubs, street life): Choose Pattaya.
Many tourists do 2 nights Bangkok + 2 nights Pattaya for the best of both worlds.
