Slug & Lettuce, Hannover Street, London

I was in London this evening and massively excited in advance of seeing Ryan Adams at the London Palladium, so I opt to have a quickish dinner at the nearby Slug & Lettuce on Hannover Street in London. After rejecting some other nearby options, McDonald's - I've got time for more than fast food and Garfunkel's - a terrible restaurant chain from previous experience, the Slug and Lettuce meets the requirement and with the branch in Cambridge having now disappeared it's something of a minor nostalgia trip. Upon entering, it's really dark and really busy; I only later realise that it's because it's 50% off food on Mondays - an added bonus.
They didn't have either my first or second choice, Steak & Kidney Pudding or Chicken Souvlaki respectively, so I had my first Philly Cheese Steak Sandwich, no idea what it's supposed to taste like, I suspect the version I had was an approximation with thinly sliced steak cooked medium in a white crusty mini baguette with melted cheese and onion. Serviceable enough but I'd like to try the real thing at some point, however no complaints as it was half price.
However the real point of the evening was the gig and having seen Ryan two times previous, tonight was the best I have seen him. He played alone with only 2 guitars and an upright piano accompanying him in the red glow of the spotlights in the dark theatre and he opened with an amazing version of this song...
