Near to both, L.BS. And E.E.H., prices are mostly reasonable than other stores (except Metro :P). Most of the times, crowded. Has no levels so, roaming with loaded trollys is easy.
It's a huge outlet on Sahar road Andheri East near Koldongari. Best part is they have valet parking available. Best time to visit is in morning around 8-9am. You will get less crowd.
