I visited this iconic bar several times over the years; its central location near the major tourist area made it a convenient place to meet up for a drink or four before heading out to see more the city. Located within the sprawling Raffles Hotel, the bar is the place to go to enjoy a Singapore Sling in the establishment where it was invented in the early 1900s (or just about any other libation you can imagine). The atmosphere is distinctly casual, with bowls of peanuts on each table and an open invitation to throw the shells on the floor. The decor is distinctly British-inspired Southeast Asian Colony: dark woods, shiny brass, woven grass fan blades on the lazily rotating fans. Although the signature drink is distinctly pricey (about $11 last time I was there) and costs extra if you want to keep the souvenir glass, the rest of the drinks are reasonably priced, as are snacks (usually I was cheap enough to simply munch down a lot of peanuts for free, but my associates enjoyed several appetizers that were quite reasonable)
I have to admit that the Singapore Sling was pretty watered down, sort of like Jell-O without the pectin to thicken it. It was worth it once just to say I have tried one, the experience being priceless and all, but if you're on a budget, I'd buy one and share it with your six best friends so you can all say you tried it but are only out a buck or two.
