I'm a 100% Starbucks girl and even though it's expensive, I still very much love it!
I usually go to the one in Elmvale as it's the closest to my place. I usually order the Green Tea Frappuccino and their White Chocolate Macadamia Nut Cookies and as always, they are very well made and delicious. Everyone there is super friendly and they gave me a free cookie one day for being a loyal customer.
The atmosphere there is definitely nice as well. There are a lot of outlets for laptops, they maintain the place very well by sweeping and wiping the tables once in a while. I don't drink coffee but I really like the smell of it while I'm there.
