Looking for Recommendations for Best Cafes that sell Matcha Lattes

I want to get recommendations for best restaurants, cafes or stores that sell good Matcha Lattes in Osaka (priority)/Tokyo.

To be clear, I am not looking to buy matcha powder for myself. I just want to do a bit of a "matcha crawl" and try prepared lattes at cafes or specialty stores if that makes sense.

Would love to hear about any specific shops that I guess have a unique flavor profile or a "must-try" specific kind of matcha latte while I am in Japan. Thanks!
