Agra Fort is still boss, the Sunday buffet comes highly recommended, even the takeaways are great as you get a complimentary beer. Obviously being on this site I only have takeaways once in a blue moon!

 The Port is weird, not much of a destination, if you last went yonks ago then there is a big fairly soulless wetherspoons around the corner.

For the old traditional curry, Agra wins, but again depends if you're limited to Chester itself or the surrounding area.
