From what I saw in the brewery, you mass pull everything even non agro mobs to some stairs, clear them, then pull to where the first big monkey boss spawns. That room has like 100 monkeys you can kill before the boss shows up. But you need some aoe or they all run away if you don't kill them fast enough. Soon as the monkey boss spawns you just leave group or whatever and reset the instance.

Monk tanks were so op with the beer toss to get agro and the hurricane kick with vengence.
