Might I ask, what are your Chicago choices? Just curious, not planning to influence you in any way.
In West Lafayette, you'll find some serviceable Barbecue at South Street Smokehouse. Here's the Roadfood review: http://www.roadfood.com/R...outh-street-smokehouse
It's good, not great 'Que, but it's as good as you're going to find in West Lafayette, Indiana on a Sunday night.
Have a great trip!
