1) It's Corktown, not Cork-town. It's a real neighborhood name.

2) I think it just depends. Saturdays are going to be busy for Eastern Market eateries. Game days/nights for any of the 3 teams are going to be busy for Downtown and Corktown, Weekends are generally busy all over.

and 3) about your first question, that's probably happening more in Midtown. Hop Cat, Jolly Pumpkin, La Feria, and even Whole Foods are all new additions to the Midtown scene. Though all have scene newbies open up.
