Really good coffee! I highly recommend

Arrived 1 hour before closing and were told they "no longer had espresso". We had entered and the baristas stared at us as we were waiting to order and didn't even greet us or offer to take our order at the register (they have 2 self-checkouts but also the option to order with them directly), which I can look past if they are occupied. But to let us order and pay and then let us know they "no longer had espresso," is baffling. Owners should make it to so people don't even have the option to order espresso drinks If they are "sold out".
No further explanation was given to "No longer have espresso."
This can mean 2 things... 1. A coffee shop is unprepared and doesn't have enough inventory which is unprofessional. 2. Baristas no longer want to make espresso based drinks so they can leave early by deterring customers
I believe it to be 2. This is not the first time we have been turned away, before it was 45 minutes before closing stating they no longer were making espresso based drinks. I understand there being a last call or turning off your machines 30 minutes before closing so they could cool down to be cleaned but 1 hour before closing and not notifying the customer before they order and pay is ridiculous.

Side note: barista did apologize and give other non-espresso recommendations and promptly refunded our order as we asked.

Currently waiting for my 2 lattes to be made.. it’s been almost 40 minutes. Doesn’t seem to be many people here, and have been given zero update or consolidation for standing here waiting. Only that “we’re a little backed up” as someone who has worked in the coffee industry for 5+ years, I’ve never seen a drink take 40+ minutes to make. Thankfully I’m not on my way to work, I probably would’ve had to walk out at this point. $18 for 2 lattes that are probably going to take an hour is a reason why I’ll never come back here.

Great study spot! Free wifi and a lot of tables in a small space! Plugs are only along wall above the high top counter seats on walls near the patio entrance, so come fully charged if possible c:

Parking: Smallish parking area, but usually able to find a spot when I go!

Had flat white, black sesame croffle and pistachio croissant. Coffee was good, the croffle was very delicious but thought the croissant was okay.

Great coffee shop to work and/or catch up. The drinks are amazing and wifi’s solid. My only request is for the music to be a little quieter…it can be hard to concentrate or talk bc the music gets rlly loud sometimes

I recently visited a big, clean coffee shop that’s perfect for working or chatting with friends. Their coffees and lattes are phenomenal! Another great feature is that they close late, which is a definite plus. I will definitely be coming back!

Everyone is using a laptop and there’s no seats.

I came here to study and do homework. It gets busy so it is hard to find a spot to sit but there is plenty of seating. There are outlets available making this coffee shop a perfect place to do homework and study. It can get noisy when others are talking with friends. Their specialty and regular coffees are delicious. I had the banana milk coffee and croissant.
