Slightly more seriously, I travel around to some different towns. I don't get to choose the towns, but there's a variety. And I refuse to cook in the hotel when there's all kinds of great restaurants to sample.
It is possible to make better choices when dining out. Shoot for the healther side of the menu, dodge the carbs, cut the sauces or get them on the side. If all else fails, go with old fashioned portion control and just cut up your meal before you even start into an 'eaten' and 'non-eaten' part.
I find that even one beer makes such self-control more difficult for me.
Also in my case, going to more expensive places helps. As I begin to run out of expense account money, I'm going to order smaller portions of simpler, and often healthier, dishes.
Obviously non of this is sufficient if you're in strict calorie-counting mode. Many of the chain restuarants will provide nutrition information online. you can look them up and work out a plan before you go. That actually helps a lot.
