Quest Connaisseur Cafe is almost under Phaya Thai BTS. It has plenty of room and offer a wide range of coffee’s. I had a V60 and a piccolo latte, I would recommend a V60 as it had plenty of depth and a good profile. The piccolo was a little weak and wasn’t to my liking but it was well made. The cafe has plenty of character and was a nice place to take a break in air conditioning from the busyness of Bangkok.
