After LOTS of research on this board, one place I really want to try is Sol de Mexico. I'm new to Chicago, will be staying downtown, and have no idea what neighborhoods are like. If I take public transportation to SdM, is it safe for a single woman in the evening? One poster somewhere referred to the neighborhood as "gritty." I'm fine with that, have hung out in the Mission in SF for years. Just want to be sure I don't walk somewhere I shouldn't. And thanks to everyone who has posted about all the Mexican options—I'm really looking forward to maximizing my too brief time thanks to you all!
