Munchies's is not really a ground breaking concept. It's kind of like the former Spoon Me from Kensignton and I've seen the concept around other cities as I've roamed.
That being said, it's a great froyo option in the nw. Especially if you're not interested in just fruit. Actually it's probably better to go else where if you are just after fruit but I personally like the mix of "bad for you" toppings on a "reasonable" frozen treat. Marble slab is delicious but swings a little far to the "omg, I can't believe I just ate that" while some other froyo might not satisfy an intense need for a treat.
The reception of this location has been amazing. Quite late on a weeknight and there is a line out the door and around the store (30+ people?) They NEVER have their frequent buyer cards and seem to be always sold out of promo stuff. Either they are struggling to manage the location or they are slammed all the time and I'm guessing it's mostly the later. The staff is not the best but as long as they stay out of your way it's a very brief interaction anyway.
I really dislike the size of the containers... because they make you over serve yourself. A reasonable serving looks so pathetic in the bowl. But I guess they do that on purpose as it's based on weight but it's evil food marketing type stuff at work there. the place is a bit expensive but if you watch your pouring you'll get out with a nice treat that won't be too hurtful to your waistline or pocket book.
