Allow me time to explain the 4 different meals here.
Hindi meals have no beef or beef products.
Halal meals must have meat that is prepared a special way starting from the
slaughtering of the animal. But, it will never include any pork or pork
materials. As the restaurants cannot provide these special meats, the
Halal meals will be made with vegetables and seafood.
Vegetarian meals have no fish, meat, or products made of these things with
protein provided by beans and tofu.
