Jim, drinks were expensive everywhere in Sing, but there was one small bar in OT which showerd football and wasnt frequented by girls, I think you could get a pitcher of tiger for a tenner or thereabouts. Hotels arent as expensive as you would think, especially if you book in advance, but you would need to research if they are guest friendly.
The health club scene there is also fun too.
Not as cheap as Thailand but you do get a bigger range of nationalities in OT: Thai, Vietnamese, Cambodian etc. Worth it for a few days if you are in the LOS, jsut for the experience.
