I had been buying different brands of ground coffee beans from several supermarkets until I chanced upon this coffee store last month.  It's called 
Coffee Lab and located at the 2nd Floor of U. P. Town Center.
I was strolling inside the mall and spotted this store.  I approached to see what it offers.
It has whole beans from different origins, mostly, imported.  I was looking for ground beans since I had no grinder yet then.  It has none; but, if requested, the grinding is free.
I'm particularly interested on the Bluenotes brand, which has "100% Single Origin Roasted Arabica Coffee" from 28 origins.
It also sells other coffee products, coffee machines, and equipment.
I didn't buy coffee beans yet; as,  I still had supplies of ground beans good for a week or so.  On my next visit, I got a 500 ml pack of Benguet origin and had it ground.  I was also considering of getting a grinder and a dripper.
So far, I've already tried 5 of the origins (Benguet, Ethiopia, Kenya, Colombia Supremo, Papua New Guinea).  There are still 25 more to try.
By the way, the salesladies, Mina, Mona, and Dianne, are friendly and accommodating.
