I have been to Boss Coffee a few times now. I was very impressed my first time because the cashier was friendly and helpful and told us to have a seat and she will bring our drinks to us. I thought that was a great touch to this shop! But, the other times I have been there they haven't been doing that. I think it makes it a welcoming environment.
The latte macchiato, iced or hot, is delicious even if you add flavor! The cold brew is very strong and has nice bite to it. I was turned off by the fact that you have to pay for whipped cream, I've never been to a shop here that does that. Also, their large only has 2 shots and an extra shot is $1, which I believe is too much especially since shots are typically pulled in twos. (Reasons why I took off 1 star)
The ambience is excellent and I like that it is bright, well-lit and has a cute patio. There is no other shop in the valley that is beautifully decorated as Boss. It's a great place to study because the booths are comfortable and the music is calm. I do wish that they would extend their hours a little longer because it is the only coffee shop in the area that is open later and is a study spot.
I definitely recommend!
