Hmm...you don't say? I'm in Muscatine for the summer so I will have to give the TJ's a shot for lunch soon. Needless to say I've been very impressed with the food options in Muscatine so far.
The one on the southend (with the fancy sign) is best! (im not sure if the northend one is even still there)
Muscatine does not have a lot of great "sit-down" restaurants, but the fast food is actually really good.
