Assembly Chef's Hall is a not a food court, but a Centralized location offers great food from Toronto's great chefs. You don't need to have long wait or pay a lot in their regular restaurants and allow you to have some of the best dishes on their menu.
The best way to experience ACH is to call a group of friends and share the dishes together. Most of the seatings are communion style and able to fit big groups.
My Yelp friends shared a few dishes together:
Bara Chirashi from Shari - sushi rice is prepared perfectly and the seafood is very fresh.
pad gra prao from Little Khao - the meat is flavourful and love the spices they used.
Spicy Sopressata Pizza from Good Son - the pizza is made to order.
They are all nicely done and taste very delicious. I have to admit the price point is higher than regular "food court", but definitely worth it.
