It pains me that one of my clients is smack in the middle between the two Indian places and one Chinese place that we order from constantly, and I can't just pop in and grab something for home at lunchtime.
TakeAways mostly open around 5 or 6pm. They have no lunch hours because they are just takeaway. You'd have to find a restaurant. Chippys are open all day as are pubs and fast food like McDonalds, BurgerKing, etc.
I've noticed that the most popular places for food are places like Greggs and Copelands and other places where its a pasty or sausage roll or sandwich to grab and go. I'm still trying to deal with the fact that most of the people around here just don't eat meals the way we do in the states.
