Visited GEM restaurant in Penang recently. They serve authentic North Indian food. The manager on duty is super friendly and provide very good service. Had tried their tandoori chicken, fish tikka, masala prawn and some naan, all these was recommended by the manager in charge. Gave a 5 out of 5 rating. Had some masala tea after dinner. The restaurant was relatively crowded even on a weekday. Recommended to call for reservations if you have group more than 5.
