Shoppers stop in Bangalore is a rich mans shopping place. Though you do get some inexpensive items but the variety is limited and you will not find some of the most renowned brands. For examples - in the perfume section, you will not find Park Avenue; in the jeans section you will find a few of the major brands missing;
I have always been to Shoppers Stop, Bangalore for window shopping ( a term used for checking out items in the shop but buying nothing at all ) strictly. But I have bought some stuff during the sales - sometimes the sales are great!
It actually depends what you want to buy - if you want branded stuff you have exclusive showrooms in Bangalore for almost all the brands. If you want apparels or generally anything - check out Commercial Street, Brigade & MG Road and now a lot of new shopping complexes have opened up (I am sorry I cant remember the names cause I am no longer living in Blore). But definitely, Shoppers Stop is worth a visit for a different kind of shopping experience.
Also must mention - it is among the top 10 meeting points in Bangalore - thats where I used to meet some special friends :-)
