I added another defination for ABC that is Appa Balwant Chowk. "Appa Balwant" is name of person and "chowk" means Road crossing. This is famous area for Books and stationary. As Pune has large number of education institutes and software and mechanical/automobile industry mostly People like to purchace books for this place.
You will get almost all books published in world. also you can have option of cheaper publications. So have choice of buying original expensive edition or leagal Indian edition. also you can buy or sell old books with reasonable rates.
Insted using of big name ("Appa Balwant Chowk") people prefer to use abbrivation as "ABC".
I will like someone to post this properly.
