I came across this review (http://www.munchpunch.com/2204/max-brenner-greenbelt-5/reviews) about their Makati branch, both plus and minus, but reading through there are more pluses.
I have been to their shop long time ago, can't remember if it was 5 or 10 years ago with two of my friends. I was impressed of the place since some of the crew were skinhead, I was skinhead that time I visited. Then I saw this apparatus that mixes chocolate inside their resto, interesting indeed. It was through my friend who brought me to the place who taught me how to properly savor a chocolate drink with its taste, texture, smell and pleasure.
Here's another review, but international, not local one about the resto in different parts of the world but mostly in the US - http://www.yelp.com/biz/max-brenner-philadelphia?start=240
Have you checked the resto lately, what was your experience?
