The Thai Terrace - Rooftop Restaurant & Cocktail Bar

You're taking the lift up Castle Car Park on Sydenham Road, which sounds grim but isn't—seventh floor opens onto a rooftop that feels properly detached from the high street bustle below. The Thai kitchen does the classics properly: pad thai that tastes like someone who knows what they're doing made it, curries with actual depth, none of that diluted stuff. Cocktails are taken seriously here, and the whole setup—tables spread across that open-air space—gives you the sort of evening you'd normally have to drive to somewhere fancier to find. Service is genuinely warm, and the fact that this many people (1,250+ reviews) rate it this highly suggests they're doing something right.
