Yes! Working at Yonge/Dundas at a job I both hated and sucked at, this place was my oasis. I'd grab my friend Erin and we'd escape the the "beautiful" Atrium and have a terribly expensive but wonderfully satisfying Booster Juice.
Lots of options, you can't really go wrong. Not only are you getting lots of fruit (albeit frozen), you're getting some sort of "boost" that actually does pick you up. It's great. Also, it's last foreeeeever. Go Booster Juice!
Another thing I like about this place is the menu is well laid out, in a clear and informative manner. You may not know anything about the 'boosters" but their benefits are clearly explained and well defined. Usually, if I'm choosing my boost I'll choose energy. Just because that makes the most sense to me.
I'd also like to point out that there used to be a flavour called Go-Mango, or Goman-go as I liked to call it. You won't find a better chain offered smoothie outside of Berkeley.
