My FAVORITE frozen yogurt hub is Menchie's!!!
Although the flavors change regularly, I can usually find at least two flavors to mix & match. I'm a choco-holic -- so, my fav combo is a chocolate/coffee/vanilla mix with spanish peanuts, coconut & topped with hot fudge!! Sounds almost like a tin roof sundae? YEP!
However, on a couple of visits, they did not have the coffee (or cappucino) flavor yogurt. Bummed ... But, I found Cake Batter flavor or cheesecake flavor is a decent substitute if need be. Samples are always available in little cups, which is a good way to figure out the perfect concoction. One of these visits, I'm going to have to try the fruit flavor frozen yogurts -- in particular, lemon & raspberry together. ... But, it just seems every time I go in there, I crave the chocolate & hot fudge experience!! Prices are based on the weight of yogurt & toppings in an ample cup. So, it can get expensive -- and you never know how much it will be until it's weighed at checkout. Be sure to pick up a Menchie's Passport -- sign up online and use your passport card with every purchase to accumulate points to get a $5 credit with every 50 points.
On my last visit to Menchie's, the store was selling "Paws" in support of the Cleveland APL (for which I volunteer) -- I bought a few "paws" that were immediately posted on their wall. The clerk was a slightly older woman (40s-50s) and she was a dynamo! She was happy, friendly, knowedgeable on flavors, specials, and the APL charity. She was a very good face for this Menchie's store in Westlake (Crocker Park).
*FYI: Menchie's is a national franchise chain of frozen yogurt stores. There are approx. 11 chains around Cleveland & east/west suburbs -- as well as where I used to live in Santa Clarita, California.
