Crazynoodle,
Nope, the CISSP is the old fashioned, "fill-in-the bubble with a #2 pencil" paper exam. Be prepared both mentally and physically as taking the exam can be quite an ordeal, particularly if you take the entire 6 hours to complete it. You can take bio-breaks, although you will be escorted to and from the restroom by one of the exam proctors.
When I took my exam, I took a couple of breaks to unload some excess caffeine. From start to finish I completed my exam in 2 hours and 20 minutes, which included the two trips to the restroom. I felt that I was prepared for the exam before sitting down for it, so I didn't take anything to snack on, although I did see a few people bringing power bars, fruit, and the like. Ice water was provided, but not coffee or anything else of a consumable nature. I ate a good breakfast beforehand and got to the hotel early so I wasn't stressed out on arrival. Like any good test-taking strategy recommends, it is a good idea to at least do a drive-by the testing site the day before to make sure you know where it is and how much traffic might delay your arrival. Test taking can be stressful enough without any extraneous interference.
IMHO, the best test taking strategy, regardless of method of delivery, is to be prepared, be relaxed, and be ready to give it your best.
Good luck,
Joe
