It was in this fut coins club that I ran into a Batarian bartender who poisoned Shepard when he served him a drink.
Batarians have a longstanding grudge against humanity see.The four-eyed Batarians were featured prominently in the first Mass Effect prequel novel, but then failed to make much of an appearance in the original game.
For the nerdier Mass Effect fans among you, those guys will be showing up a lot more often in Mass Effect 2's border planets, since they tend to operate off the grid and outside the Citadel's influence.
