Usmania International Restaurant
Usmania is a Pakistani restaurant expressing authentic Pakistani taste in both its interior and food. The menu features about a hundred dishes, ranging from whole wheat bread, lamb, beef or chicken, but does not offer any pork dishes or alcoholic beverages, which are prohibited by the Koran. Inside the restaurant, you will find a variety of Pakistani decorations such as traditional shishas (water pipes) and silk carpets. Beef kebabs and tandoori chicken are favorites among Korean diners.
