Basically, the only bad thing I have to say about cool beans cafe is the limited seating they have during prime lunch and dinner hours. So much of the dining area is eaten up by a cooking-class area that I've literally never seen in use in all of my various visits. At peak meal times, be prepared to not be able to find a table at all-- which speaks volumes for the quality of food, but not so much for their forethought in seating.
The cranberry chicken salad sandwich is my go-to menu item hands down. It is the BEST chicken salad sandwich I have ever had. All of their sandwiches are great, but this one is just leaps and bounds above the rest! Whenever I am nearby, I'll make a special trip out to Medina JUST for this sandwich. They also have a wonderful selection of coffees, drinks, pastries, and desserts. The service has always been great. The staff members and kind and they really put effort into helping you out. The prices are decent for cafe-type dining, and drinks are reasonably priced for a coffee shop.
There is a lot of free parking nearby, and the little square in downtown Medina is a great place to spend a few hours walking around.
