Compared to the other grottos in Markham/ York Region area, this location is more spacious and brighter. There's usually not too many people and tables are wide enough so good place to study.
Drinks wise it's pretty standard. Nothing too out of the ordinary, but there are a few items on the menu that's never available (like the white chocolate drinks) so I'm not sure why it's still on their menu, maybe other locations have it. Food also ok. Not bad but nothing special. Tapioca consistency is normally good with some chewiness but not hard or too soft.
Washrooms are clean. Service is decent. Good selection of magazines. Nice decor.
Overall great place to just have some time to chill or study.
