Informal (Interview?) With CEO of Boutique Investment Bank

Hey guys,

So I did some research and found that in my situation, the best would route into IB would be to network. So I made a spreadsheet and hit the phones. Upon calling a particular boutique, I spoke to someone who said they only hire people with an MBA. I explained that I only have a degree, and he asked what was the purpose of the call. I explained my technique and he asked me to send him a CV and he would see if any of his friends could help me out (I think he approved of my attitude). After I sent it he said "Why don't you come into the office next week for a chat at 'so and so' time?"
Turns out the guy I was talking to was the CEO.

So my question is; how do I make the most out this informal meeting?
What should I ask?
Should I try to close and obtain a position?

(I have experience in Business Development, but none in Finance, 2.1 Degree in International Business)

Thanks in advance guys.
