I won't lie - I don't enjoy flying from Heathrow. It's chaotic; there's not enough seating; and, inevitably, I end up being assigned a gate that requires a tram and then a shuttle making me wonder why they can't get the planes a little closer to the terminal. But I love that this terminal has one (maybe more than one?) location of M&S Simply Food. When we were flying from Heathrow earlier this month, I wanted a bite to eat before our flight, but I wanted something healthy-ish, easy, and quick. M&S Simply Food is a chain of convenience grocery stores owned by Marks & Spencer. They have a lot of sandwiches, fruit, wraps, salads, baked goods, snacks, and more. We got a sandwich, some sushi, some snacks, and waters. Healthy-ish, easy, and quick. read more
