I have been going to La Perle for as long as I can remember. Let's start by the obvious: some of the dishes are incredible good. The peanut butter dumplings alone are worth driving from Terrebonne for. I also recommend the general Tao chicken, the black pepper chicken, the beef and broccoli and I really like the fried squid (though I understand not everyone likes squid.)
Now, I hadn't gone to La Perle in a few years and went last night. The service has horrendous. First off it really feels like they are trying to cram as many people as possible in the restaurant. Secondly, the waiter came, gave us a sheet and said "fill it in, I'll be back" and that was it. Our order of beer was forgotten. We got the won ton soup after 20 minutes. The appetizers took an additional 30 minutes. And the main course maybe another 40 after we got the appetizers. We asked for more dishes which were forgotten. We asked for tea which was forgotten. Honestly it just felt like too few waiters, too many clients.
I hope this was a one time incident because the food is really good!
