Can't say for sure, Theo, but at the I-65/U.S.30 interchange (in Valpo, err, Valparaiso), there is a bunch of restaurants, shopping, etc. I would think there would be a Chinese buffet in there somewhere. I work mostly in Tippecanoe County (pop. ~150k), and there's gotta be at least a dozen Chinese buffets there.
Thank you for the Valpo heads up.. I am staying at that intersection I believe - in the Courtyard Inn, so I will look for a buffet round there. I will be so glad to complete the purchase of my house, so I can start doing Indy things..
