For a great night out with food and entertainment try Tawangdang, it's a huge place near Rama 3. Holds about 1500 people, probably 90% Thai and they are having a ball. It brews it's own beer as well, it's a German style beer hall with all sorts of entertainmnet, from singers and dancers to magicians and acrobats. The food is good as well, mainly due to the mostly Thai crowd. Most nights it's at least 80% full a swell, so always a good atmosphere.
