Etiquette Bangaloreans are informal. But in some homes you must take off your shoes before entering. A pile of shoes at the front door is a good indication. No footwear in temples. It is fashionable to be late in Bangalore.
Mixed drinks are popular.
Good idea to grab a bite before you go. Dinner also signals the end of the party. So it isn't impolite to eat and run. Some restaurants stay open till midnight. Eating out after pub closing is best in a 24 hour coffee shop in bigger hotels.
