I’m not going to challenge you on your dislike of Arun’s, because I haven’t been there in years. Last time I went, it was wonderful, but perhaps it’s changed.
However, calling it a "dicey" area is just plain wrong. It is indeed far from downtown, and difficult to get to without a car, but there’s nothing dangerous about the neighborhood and no one should be discouraged from going for that reason. I say this as someone who grew up on Chicago’s North Side and lived there until recently. I consider myself an expert on Chicago’s neighborhoods.
For great Chicago food that’s really in a dicey location, I recommend Leon’s BBQ on Halsted and 59th, in the Engelwood area of the South Side (the neighborhood with Chicago’s highest murder rate). There aren’t any tables – and the servers are behind bullet-proof glass. I used to go there, but that was before I had a wife and kids. (There are other Leon’s locations in less dangerous neighborhoods, as well).
