I equate Orchid Garden to the Wal Mart of DIm Sum.
It is large, busy, open all the time, and has it all. It is certainly not the best dim sum available. However, you continue to frequent it due to its convenience and mass appeal.
Prices change depending on whether or not you are Chinese. That is certainly annoying.
Since it is generally busy, the food is usually hot. That's a major plus!
I been many times, I'll go again - fully knowing, it's not the best but just fine.
