Some folk dress for it, but its not essential. This is Birmingham. The curry is usually excellent, and many are unlicensed, so bring your own beer if sitting in. It's absolutely huge inside and very friendly. Prices are good and beer isn't bad either.
Food is very cheap and very good.
Since it was taken over by the goose chain recently, it has improved no end and there are lots more people in it now. Brilliant sunday lunchtime pub. Plenty of ales with reasonable prices. Can get very busy. Shows sports on big screen.
