I was thinking about when I lived in London on my own, in my early twenties. It was a shared flat and although we had a reasonable kitchen, I wasn't much of a cook back then. But I loved good food! I used to treat myself once (sometimes twice!) a week by going to a restaurant alone. I really enjoyed it immensely. I'm not talking here about informal cafes or fast food outlets for lunch, but fairly formal restaurants in the evening. Have you ever done that?
