I finished Fast Food Nation yesterday. That was a very good book. It gave a lot of interesting facts about the fast food industry and especially about the meat packing industry. The facts were presented in a non-textbook-ish way that made it very compelling.
This book has only reinforced my vegetarinaism and has shown me how horrible the meat packing industry is. Their concern for their animals, employees, and customers is almost nonexistent compared to their concern about profits.
Anyway, I highly recommend this book. You'll definitely learn something.
