It's really really near my house. I found it by chance when I went out and bought some takeout lunch. I normally don't drink coffee so I ordered matcha green tea latte. The barista said they use same matcha powder from Starbucks, and their coffee beans are from their own farm in north. The taste is rich and creamy, smell some fragrance of matcha, and not too sweet. I don't like the tea too sweet, it will ruin the fragrance and taste of the tea itself. A little pricey compare to the local coffee stall around there, but compare to its quality, it's not expensive. The matcha latte I ordered was around 55 THB.
The only flaw I see is the closing time is too early, should be around 7 or 8.00PM.
