Slough has an image problem, immortalized by John Betjeman's poem urging friendly bombs and by Ricky Gervais's portrayal of its soul-crushing office culture in The Office. The reality is more interesting than the caricature. Slough is one of the most ethnically diverse towns in Britain and has a genuine economic energy driven by its trading estate, one of the largest in single private ownership in Europe, and its position on the Heathrow corridor.
The town center itself is functional rather than charming, but Slough's great advantage is proximity. Windsor Castle is literally a 10-minute bus ride away, Eton College is across the bridge, and the Thames Path runs through nearby countryside. The Slough trading estate has its own industrial heritage interest if you have a taste for that sort of thing, and the forthcoming Elizabeth Line improvements are making the town increasingly accessible from central London.
If you find yourself in Slough, the real draw is the food. The Farnham Road stretch is packed with Pakistani, Indian, and Polish restaurants and grocery shops that offer some of the most authentic and affordable cooking in the Thames Valley. Do not judge this town by its reputation.
