It's not a hard and fast rule, but my hubbie and I will usually order something different, and taste the others. Sometimes, it results in a different order on our next visit. For example, we went to a local thai restaurant, and he had something I just loved. Next time we went, that's what I ordered - he went back to his normal favorite. (pad thai).

Husband is much less adventuresome than I am - I like trying new restaurants and new dishes. He likes his favorites, and rarely ventures far from them. Occasionally, of course, this has backfired on me, and I got a truly repulsive meal

One of the reasons I love traveling is that it forces him to try new restaurants, if not new dishes. How many different pubs in the UK/Ireland has he been to? 50? He ordered fish-n-chips or beef and guinness pie at all of them
