Neither. They both chuck out unhealthy, expensive, oversized crap.
I work in London, and the choice for lunchtime snacks is phenomenal. There are loads of big chains - Itsu, Pret a Manger, Starbucks, Eat, Salade etc, then there are smaller chains - Abokado, Leon, Chilango, Wasabi, then there loads of independent sandwich shops and then there are the market stalls (Leather Lane nearest for me) that have all sorts of World food. And then there are restaurants of all shape and variety from Pie and Mash, greasy spoons to Michelin starred restaurants. All a short walk from my office.
And then there's the office canteen which is pretty splendid, subsidised (a bit), on the 9th floor of my building and with a roof terrace.
But I HATE queuing for food. So I often spend my lunchtimes wandering aimlessly from establishment to establishment trying to find one without a queue. And then ending up in the first one I went into because that was what I really fancied in the first place.
