I was traveling this route about 6 weeks ago, and we stopped in a great BBQ joint in Forrest City, AR (about an hour west of Memphis in between Memphis and Little Rock, just off of I-40). Hickory House BBQ, 918 North Washington St., Forrest City, AR.
The food was great, and very inexpensive. A down home BBQ place. Filled with local color, with pictures of their family in the back of the restaurant. I had BBQ; excellent.
Can't think of anything "great" between Conway and Little Rock. There's Catfish Country (http://www.catfishcountryconnection.com/) between Conway and Morrilton and it's only open on the weekends.
For a change of pace, in Little Rock you might want to try the cafe in the Presidential Library, Cafe 40. We went in the spring with 8 teenagers (all were well behaved). The sandwiches are really good.
Another vote for Craigs! if you're going between LR and Memphis.
I don't have my references in front of me, but some time back we found a wonderful catfish place at exit #202. Go 2 miles south from I-40, then 2 miles east on the US highway and turn right just before the river. On your left (about 300 yards from the highway) is a great place for catfish, but they are only open Thursday-Saturday as I recall.
