This halal restaurant specialising in Bengali and Punjabi cuisines is christened Mustard because the spice is used extensively in both cuisines. For instance, mustard oil is often used in place of coconut oil in Bengali cooking. Try their maacher cutlet – deep-fried fish croquettes served with a house-made fermented mustard sauce called Kashundi, which tastes strong and spicy. All food is made to order, but is so worth the wait.
