Obviously, the highlight of St. Andrews is the golf course, but the city actually offers a lot more in the way of nightlife and dining.
Quick Tips: If you plan on going out to the bars, make sure that you realize that they normally close at 12am or, in some cases, 1am. Don't start your night too late.
Best Way To Get Around: Definitely use public transportation. In St. Andrews, just walk. Nothing is too far. You can pretty much walk everywhere in Edinburgh as well, but bus service is easy and cheap.
