I had tried The Perf Blend smoothies sometime back. I called them ahead, placed the order, and went to collect it (It’s operated on Take-away/delivery model, and since the place was close to my home, I opted for take away).
I had also availed Sudharshan’s advise on choosing the blend.
Smoothie: It tasted well, but the consistency was not that of a smoothie. It was more like a juice.
Having said that, since it’s quite new, and has a passionate foodie behind it, I’m sure it’ll only get better and better from here.
