Pros:  It's a great, laid back type of atmosphere.  In fact, it's SO casual, most women won't even assosiate it with a first date.  Why is that so good?  It cuts out TONS of barriers.  When women conciously think they are on a first date, they put up barriers like: "no sex on the first date," "gotta play hard to get," etc.  It's also cheap if your a broke college student

Cons: It's becoming more and more popular now-a-days so it might become the next version of "dinner and a movie."  I doubt it though.  

Notes:  You might want to work on your conversational skills before trying this one, because thats all that there is to do.  Work on transitions, keeping the conversation light, fun, and you should be golden.
