My first stop for the second coffee passport and I say 3.5 stars. The lack of a 4 or 5 star review is mainly for the friendliness which could have nicer, normally one would expect the barista to be sort of excited at least for giving me my first stamp, in fact what I got was the exact opposite. The staff didn't seem all that happy when I came up with my passport saying "it wasn't good for them". When I started saying that thanks to the first passport I had returned to locations I would otherwise never have been to, they didn't seem to be all that in to having the conversation. But on the other hand, when we were leaving a different barista was friendly and asked us how our coffee was etc.
While I was a fan of Quaff, R Squared does seem to be it's cleaner and brighter brother/sister? Seating seems to be ample and very roomy which I'm always a fan of and free wifi is a plus too! . Like Vivek mentions in his review, the vintage movie posters were a nice addition in the back.
I got a pistachio biscotti which could have been cheaper but was delicious nonetheless. My latte was well done and went down smooth and my friend's cappuccino did have some nice art going for it.
I would give them another shot as I did like my drink, but after being spoiled by friendly staff at most other locations, R squared gets points off for lack of love towards the Coffee Passport program, which I happen to love.
