Grid Coffee

Great place for matcha, atmosphere, and service. Good range of dairy alternatives: soy, almond, oat, coconut. 10/10 would come again if I was a local.

Not an expert on coffee, but the lattes were fine for me. However, the service and atmosphere is perfect. The minimal-style interior design and quiet environment is perfect, especially no music & no loud conversation. Good place for study and work without headphones.

Not for coffee people. If the barista said Dalgona coffee is their best seller, you better think twice ordering. Ordered Kyoto cold brew (tastes like old stock coffee), & Passionfruit Espresso Tonic. I asked the barista why my drink doesn’t have that tonic water taste. Barista said they use sparkling water for tonic water (It’s like that’s what they’ve been doing). No apologies received from the barista. So, I just shook my head and left. There are better coffee shops around the area (at least two across the street. Better go there. Very disappointed.

Great coffee every time I am here! I live 30 mins away but always willing to make the drive because their coffee is just that great. I find that most coffee shops either have watered down coffee or add TOO MUCH ice to their drinks leaving nothing but a sip of actual coffee in the cup. Grid Coffee's proportions are great and the atmosphere is unique and a tranquil place to study and chill.

Great coffee and vibe! (Made the review low so that managers notice~~ Will take it down soon) A note I would suggest managers to have at least 2 people in the morning shift as it got pretty busy and I noticed only one person working which made wait times pretty long/ looks stressful for the person working and lowkey me as I come here before work. I came yesterday and there were 2 people and I got my coffee on time and made my morning a lot more relaxed.

Grid coffee is a spot with great coffee and environment for chatting or getting some work done.

I went on Saturday at around 9 AM and it wasn’t busy yet. I was able to order right away and get my order within a few minutes. I stayed about 2 hours and it definitely got busier over time.

For the drink, I got the Einspanner latte with oat milk. The cream top was sweet, but once you mix it, it’s the right balance. I’d recommend this and would get it again!

I was able to grab the table with an outlet right behind me. There was a lot of space for a laptop. There’s also free WiFi available, but it was a bit spotty. The noise level was moderate to high, because the music was loud and there were a lot of customers.

The store is located in a shared plaza. There’s plenty of parking spots available before and after my visit.

They accept American Express here!
