Theyre literally open 24 hours. This is my go to place for late Chinese food. I can't say enough about this place as I've been going to this since I've moved to Mississauga back in early 2000. And even now the food is still as great as before. They have dim sum for cheap and I usually go on the weekend. The vest is very tacky as the previous yelper review below and the atmosphere can be modernised but if you can get over that , the food will blow you away. I definitely recommend this place if you need your Chinese food fix.
