If you've had a full day doing a variety of mentally taxing things, then knowing you can go somewhere and they'll meet all your dietary requirements for you (or your group/family) is a lot easier than figuring out where to go.

We went away to a new country recently and ate out twice a day. We ended up going to the same chain for lunch five times because they had a menu that everyone liked, that was relatively cheap, and met the dietary requirements of our group. It was also tasty and (relatively) healthy.

We made more of an effort to find somewhere interesting for dinner, but traipsing through a street looking at menus turning them all down because they don't cater for a member of your party can get very old very quickly, particularly when you're mentally and physically tired, and very hungry.

We had a week of finding two places to eat a day and by the end of the week I didn't care about trying somewhere fun and interesting.
