If you are lucky you would get parking in the roundabout opp Regal Cinema

Just search for trip advisor a hotel around colaba causeway, there are at least five high rated hotels. Happy hunting.

The easiest way from Bandra is to take the train from. Bandra station to Chhatrapati Shivaji Terminus . Then you walk towards the south to Colaba Causeway taking Dr Dadabhai Naoroji road . This is a nice shopping walk if after 11ham as you will meet a lot of street vendors along this road . Quite interesting and reasonable street shopping. At some time take the Mahatma Gandhi road near Flora Fountain.Nice building architecture in a Gothic style can be seen around. You will reach Jehangir Art Gallery and keep heading south till you reach Wellington fountain. A huge road junction . You will need to cross the roads and head towards Cafe Mondegar. At Cafe Mondegar, you are at the beginning of Colaba Causeway, the shopping attraction of the area. Another option from Chhatrapati Shivaji Terminus is to take a taxi but you will miss the contact with the nice people of Mumbai.
