Cart Array- Where is the option data and price?

I see the cart array in $_SESSION[cart] and the cart's discrete code ([cart] => Array ( [30:594.597] => 2 [30:595.597] => 1 [49:612.616] => 1 )) but what how do I decipher the product code, options selected and price from this? Or is that stored somewhere else?

30:595.597

30 is the product id
595 and 597 are option value ids

Thanks, I just opened up the database and figured it out.
