I've reviewed Cups at 5418 Yonge Street location before so this is review would be on the differences I've noticed between the two locations.
Quality wise the shaved ice from both places are super delicious! My first exposure to Korean shaved ice is through Cups and I still recommend this over other shaved ice place to all my friends.
This particular location has more seating space though compared to the 5418 Finch location, enough to handle multiple larger groups (I went with a group of 8 before), as long as the place isnt already packed with other patrons.
I noticed that the small shaved ice sizes here are still served in bowls whereas the other place serves their small shaved ice in clear tall plastic containers. I like the bowl version better as it allows me to dig around and mix easier.
Sizing of the shaved ice is a bit confusing. I recently ordered the Oreo shaved ice in large, and the size of the bowl looks just as big as my friend's small Oreo shaved ice. I asked the employee there and he said that depending on the type of shaved ice the bowl sizing is different. So my large Oreo shaved ice actually used the same bowl as a small shaved ice of tiramisu. Just something to consider when you're ordering. Unless you're a frequent customer and remember things, I would ask to see the size of the bowl before ordering.
The Oreo shaved ice is to die for. Definite must try.
