Parkway Parade once produced a booklet promoting over 40 food-related shops within its premises. However, there really isn't much that's really good there. For cheap eats, the basement food court is still better than Banquet up on the 3rd floor. The Nasi Padang stall is reasonably OK, although the stuff it offers seems more Chinese than real nasi padang. See prawn paste chicken and long beans and omelette in picture above.
They have quite a variety of dishes. I remember the rendang is not bad too.
