Finding your way around Bengaluru can be difficult at times. In certain areas, roads are named after their widths (eg 80 Feet Rd). The city also follows a system of mains and crosses: 3rd Cross, 5th Main, Residency Rd, for example, refers to the third lane on the fifth street branching off Residency Rd. New affluent pockets are springing up across the city, including the ritzy suburbs of Indirangar, JP Nagar, Koramangala and Whitefield – all with Western-style malls, nightlife and restaurants.
