What People Are Saying
from Google"smooth velvety coffee, with pretty good sandwiches ! I wanted empanada but those do take longer (15min) panini was however solid! It’s spacious are with lots of people studying or hanging out. Cool little shop inside too for mountain climber enthusiasts"
"The barista filled my coffee cup to almost. overflowing. I asked her to give me a larger cap and she refused saying she did not want to waste a cup. She said that she could put the cap on herself. She did not apologize. The coffee spilled when I tried to drink it. I was annoyed by this poor customer service."
"Good food! Had a great time coming here with some friends after a local concert."
"Came to enjoy a coffee with my book and ended up sandwiched in between two Zoom meetings. It’s a shame the shop allows the cafe to be a conference room with audible calls."
"The environment is incredible, nice and open with outside seating as well. The danish and croissant were tasty, but no offer to heat them up, which was a bit odd. Still, an amazing place!"
