Interesting...
Most restaurants/takeaways in my area score a lowly 1 and a few score 2 (I've used them all!), then there's a jump to 4 for a couple ( I was delighted to see that my favourite, which is run by Nepalese, is one of them), and the one I've been frequenting for decades scores a fantastic 5. That's the only 5 among the curry houses though.
Surprisingly all the kebab shops score 3.
My butcher scores a 5, too, so overall I'm a) surpirsed and b) pleased.
