This place offers pre-marinaded meats as well as cooked food. I haven't tried the cooked food as yet so I can't comment on that.
They have quite a selection for pre-marinaded meats: chicken wings, drumsticks, chicken cubes , lamb, salmon etc.
Meats are charged by the pound; price is a bit expensive but it's the convenience that you are paying for and you can choose however much quantity you want.
