I like Menchies more than Yogurty's for some reason. I feel like Menchies has more toppings and more flavours that I like - sour apple, watermelon and that kind of tarty goodness.
This location is usually pretty busy but I've never had to wait in line. Take your time and try every flavour, there are taster cups available and no one is watching.
TIP: wait until the first blob of yogurt comes out of the machine - it's usually melted and soggy. Whatever comes after is nice and frozen and won't leave you with a yogurt juice...
I think I said this in my Yogurty's review, but from my experience I do not like adding chocolate to cold things (ice cream, fro-yo, etc) because it hardens and kind of crumbles in your mouth instead of melting. My favourite toppings here are chopped cashews, cookie dough and cheesecake bits, bobba (lychee/strawberry/pineapple/mango/orange - looks and feels like HUGE caviar bubbles, except with sweet gooeyness inside instead of fishy gooeyness), and maybe some fruits :)
