Avon Gorge by Hotel du Vin

You're perched on the edge of one of Britain's most dramatic gorges, nursing a well-made martini while the Suspension Bridge frames your evening perfectly. The terrace here is genuinely spectacular when weather permits, though even inside the floor-to-ceiling windows make the most of that million-pound view. The cocktails lean classic with competent execution, and while you're definitely paying Clifton prices (think £12+ for most drinks), the setting somewhat justifies it. Staff know their stuff and the wine list reflects the Hotel du Vin pedigree. It's the sort of place that works equally well for impressing visiting relatives or a romantic drink before dinner, though avoid peak tourist hours unless you fancy queueing behind coach parties wielding selfie sticks.
