A cozy corner immediately north of the Indiana Historic Landmarks Foundation Headquarters.
According to the leasing office, this side of the retail frontage (the northern half) is a residents social area. The Left Bank will be in the southern portion of the space, and looking through the windows, it appears that there is no strict partition (a two-sided fireplace roughly divides the space). EDIT (4/4/10): The sidewalks are done and you can now walk right up and look in the windows. There is definitely a full wall separating the Left Bank Cafe from the rest of the space. The Left Bank will only occupy about one-third of the canal-front space to boot. Very unfortunate.
