Route 66

Route 66 is on Royal City Avenue, known as RCA, off Rama 9 Road in Bangkok. RCA is a strip of big nightclubs. Mello Yello, Castro, Led, Taksura, Hobb and Amnesia are all close, so it is easy to compare rooms. A Grab or taxi from Sukhumvit is the usual way to get there.

It is an RCA institution with several rooms, and the crowd is mostly Thai. That is the main thing to know: it suits people who want to see Bangkok's club scene as young Thais do, with a loud, late atmosphere, rather than a punter looking for company.

Yes, foreigners are welcome at RCA clubs, though you may be one of few. You will need ID, so bring your passport or a clear copy, since everyone must be 20 or over. Going with Thai friends makes the night easier, because menus and signs may be in Thai only.

Both are on RCA with a mostly Thai crowd. Onyx is a big EDM club, while Route 66 is an institution with several rooms, so you can move between spaces if one is too packed. Pick Onyx for the dance floor and Route 66 for variety within one venue.

Not as a first stop. It is loud and late, with a Thai-heavy crowd and a door that checks ID. For a first night, the Sukhumvit tourist clubs around Soi 11 are easier. RCA works best once you know your way around, or with a group or a Thai friend.

Smart casual works: jeans and a decent shirt or T-shirt, with clean trainers or shoes. Avoid flip-flops, shorts and sleeveless tops, which many Bangkok clubs refuse. RCA is more relaxed than the hotel clubs, but dressing up a little means you will not be turned away. Bags are usually checked on the way in.

Note the fire exits when you arrive, watch your drink being poured and keep your phone in a front pocket. Avoid any argument with a local, even if you are right, since a small scuffle can involve friends and staff. Police sometimes check ID and drugs at clubs, so never take drugs.

Go with a group, arrive when the rooms are filling and spend time in more than one room. Book a table if you want space, and ask at the door about cover and table costs. VIP members see what a table costs and when the club fills on the venue listing.
