Hong Kong is a major city and as such you can find all sorts of cuisines and fast food joints all over the city. Local food of Hong Kong is typically south east Asian. Wontons are a very popular addition to soup or rice, with a stuffing of meat; sweet and sour pork combines flavours true to the region deliciously; fish balls or shrimp and chicken balls, deep cried stuffed meat balls, are a hugely popular street food; and the rickshaw noodles are a favourite fast food among the locals. Hong Kong is heaven if you're a foodie, and exploring the city will bring you across some amazing local foods.
Indian food options are decent in Hong Kong, though not too many. Namaste Kitchen (Queens Road West), Central Indian Restaurant (Wing Lok Street), and Bombay Dreams (Wyndham Street) are some of the popular Indian joints. Sangeetha Vegetarian Restaurant (Wing On Plaza), Branto Pure Veg Indian Food (Lock Road) serve very good vegetarian food, and Smrat Pure Veg (Nathan Road) serves jain food.
