The Sonic at this location is terrible, go somewhere else. The ice cream is never filled to the top of the container, drinks aren't made properly (too much vanilla flavoring, etc.), they somehow mess up making things that have a standardized formula for every store.
Fantastic atmosphere and real authentic cuisine, Thai House is the best place in Lawrence to introduce yourself to Thai food. Their menu contains a huge variety of dishes, all of which come super fast and in generous portions. The service there is great too, highly recommended!
