After entering get to the end of the floor and pull one of the patroling orks.
There will be 3 orks coming at you! If they are down an Elite-Master is attacking you. (He can be mezzed, stunned, rootet, feared etc so he's no big deal)
Take him down and loot the armor. Now you can move around without being attacked. just loot every chest in the rooms to the left and right. There can be Mithrilflakes in it.
Now for the first boss: This works only for ranged classes (Hunters, Rk, LM)
Enter the room and hide at the side until the orks move out of the room.
After that jump on these thingys on the right wall. The adds should be in exploit now. The cook is still standing above you and can be attacked easily

just go all out!
After some time he'll jump down and also be in exploit. But during his special moves he can be attacked so make sure to dish out some dmg while he's talking
(You should bring some things to remove wounds as the fireDoT can get nasty)
This earns you some flakes, a T3 relic, a medaillon and a good chance for a second age weapon (well unfortunatly its lvl60)
Have fun
