Gurgling generally (not always) indicates a venting problem.

Thanks for the replies. The sink is on the 2nd floor and about 3'-4' from the main waste pipe, which is vented on the roof. I don't get any gurgling from any other sinks in the house. Is it possible that this 4' run to the waste pipe needs its own vent? If that is the case I might just live with the gurgling because I would have to cut into a cast iron pipe and that really doesn't interest me. Thanks for any additional help!

It is either a poorly vented p-trap or, an s-trap.
A partial clog may be involved.

OK. I took everyone's advice and popped open the p-trap and guess what, not clogged at all. That was surprising. So then I detached the pipe running from the sink to the p-trap and found that that was where the clog was. The pipe had about 1 centimeter hole where the water could go through. So took apart all the piping and gave it a good cleaning. I just installed the sink last year and I can't believe how dirty it got so quickly. I've used drain cleaner and that did nothing. Maybe I just used the wrong type of drain cleaner. Oh well. Cleaned it the good old fashioned way. Thanks for everyone's help.

As you found out, drain cleaners often don't do much...they are best avoided - save your money.
