May I suggest that we go to Longhorn Steakhouse after the parade? There are several reasons for this suggestion. They have a good selection of food. Not sure if this one has a buffet or not. The restaurant is also outside of the core part of the city and away from the parade area. At the end of the parade, we can take US 141 South, cross I-16, turn right on the first road which is Pinehill, then right again on the first road which is Travel Center Blvd.
There's also a Golden Corral that's just a short distance beyond the Applebee's where we dined last year. A little closer in and might be more crowded.
Any other suggestions?
