Well, Simon, I don't like to answer with a sort of non-answer, but thought I might give you what info I could. I lived near, by near I mean and hour and a half or so drive away in Jackson WY, Idaho Falls (IF) a few years ago, and it wasn't somewhere you went to eat. We went there quite a bit to shop, not because the shopping was great but because there was a greater variety of stores and selections compared to Jackson (population 9,577). So I can't give you any recommendations. The last time I ate there was a place near the river and falls, and the most memorable part of the meal was the mouse the staff had to corral and remove from the dining room. They've got some chains like an Outback and such, but I'm not aware of any buzz restaurants.
That having been said, you'll be less than 2 hours from Jackson which is a ski resort town in Wyoming in the Teton Valley. Gorgeous scenery on the drive in and in town and in the valley. The Snake River Grille is a well regarded restaurant there, as are the Bistro and Trio and Koshu. If you can fit it into your schedule I'd recommend a few days there, though you'll be in the shoulder season so you should check before you go and see if things are open -- the town gets very quiet for a short time between ski season and summer tourist season, and some places will close for a week or two for some time off. The good thing is that rooms are cheaper that time of year.
Again sorry I can't address your original question very well but maybe this helps better than crickets.
