M&S Foodhall

You'll find yourself in the Renfrew Road retail park grabbing far more than you planned to. The Foodhall format means you're not trudging round endless aisles—it's focused, it's quick, and the produce actually looks fresh. The deli counter is where locals linger; proper sandwiches made to order, a decent cheese selection, and the kind of prepared meals that actually taste like someone's made them rather than a machine. Prices sit comfortably mid-range, which means you're paying a bit more than Tesco but getting something noticeably better in return.
