The location of the Bangkok Cha-Da isn't great unless the nightlife you're looking for is nightclubs aimed at Thais. I've had some great nights on Ratchada but unless you speak a little Thai you'll be leaving the clubs on your lonesome. It's a great area for soapy massage joints but you'd be looking at $100 minimum for a 90 minute session on the premises, take-outs will cost considerably more.

Most guys aim to be at the lower end of Sukhumvit Rd, you've got Nana Plaza on Soi 4 and Soi Cowboy just off Soi 21 so anywhere between or around there will see you right plus no language skills required, just cash.
