Once you go through the hole in the wall and complete the assault course to get to the coffee house, the fun can begin. The venue is small, quaint, lovely. The service is high quality. Note to impatient people, don't come here and expect your coffee to be served to you immediately, even if you are the only ones in the venue. They take their time here because you are getting top quality, artisan coffee. Expect to wait 15-20 minutes for your drink. But the wait doesn't matter. The venue is peaceful and there is WiFi for all you phone addicts. The coffee itself is outstanding. My partner and I sat here and shared four different coffees over the course of about 90 minutes. All were completely different, hot and cold, and full of diverse flavours. During that time we only saw Europeans visit the venue. I don't think this kind of place appeals to Vietnamese people who just want quick and cheap and not so refined. If you are a coffee connoisseur, this is the place to visit. And take some away with you like I did, they sell different blends from around Vietnam. You won't regret it.
