Here's a dining tip: always order fish.
You're paying for this meal, so don't let the chef get off lightly by just chucking a steak on the hotplate. Make him work for it. Make him scale the blighter, make him fillet it, make him live with the fishy aromas in his kitchen for days... make him do all the things you can't be bothered to do in your own kitchen.
Add to this already compelling list, the fact that fish is good for you, the fact that it's (in our list below, anyway) sustainably and ethically sourced... but more than any of that, just order it because it tastes so darned good.
