Something doesn’t add up on this blight-infested stretch of storefronts in Oakland’s Eastlake neighborhood.

The aquarium store doesn’t sell aquariums. The sports bar sits beneath a crisp new awning but never seems to open during posted hours. The cafe doesn’t advertise coffee, though the manager will make some if necessary.

The real draw, for those in the know, is the “fish game.”

On a recent afternoon, three men huddled over a bulky video game in the cafe, slapping a button as fast as their wrists allowed. The gamers’ eyes were fixed on a screen about the size of a pool table as they settled in for the long haul. One man sipped from a Big Gulp, another from a jug of watermelon juice cocktail.
