I used to like going to Regal because of the good food and the ease we could get a table, maybe due to the large size of the restaurant and the high price of the food. If you're with a senior citizen, you will get 20% off, which brings down the price. I do enjoy their sticky rice as well - very tasty.
However, after my last experience, I will never return again. It has fallen into the trap of many a chinese dim sum restaurant before it - once it's popular, it's impossible to get a seat, unless you know someone. Really, it's like going to a night club, lining up for no reason while you watch group after group skip the line and go in front of you. Seriously, on a weekend morning, when I'm hungry, there are just way too many other nice, good dim sum restaurants out there, especially in Scarborough, for me to waste my time here. I would suggest you do the same, unless you can arrive there before 10:30am.
