the best chickens for sunday lunch?

i am thinking about getting some more chickens,but just for the pot.
any suggestions helpful.
i currently only have laying hens.
crested legbar,speckled sussex and light sussex.i got these as a utility breed,but is there another breed that would be ideal for the pot?

Hubbards are superb for the table. Just don't seem to take very good care of themselves if you were thinking of keeping a few back for breeding from and go off their legs quickly if you don't restrict their diet.
But they knock the socks off any pure breed when it comes to growth. Flavour is good too.
