Fine Dining & Hamburger Etiquette

I recently visited One Restaurant at The Hazelton Hotel I ordered "The Ultimate street Burger" I wanted to see if it really was the ultimate burger and worth the $28 I paid for it.

Before it was delivered to my table I did not give one thought to how I was going to eat it.
Until my companion asked "are you going to pick it up with your hands and eat it"

I paused and thought for a mere second and relied "Yes!... it is called The Ultimate Street Burger" is it not? Last time I was served a burger I was not given utensils.

So the question I ask is this : What is the proper etiquette when eating foods such as hamburgers and fries when they are served in such an upscale joint?
