I'm pretty basic with my coffees and always opt for a hot vanilla latte ($5.75). Visited Grid Coffee on a Sunday late morning and almost all the indoor seating was occupied. The decor and space is very minimal and relaxed. Good coffee and a nice area to hangout or study. Only downfall is the chairs have no backing so if you have a bad back, this may not be the place for you to hang around. Definitely will be back to try the strawberry caffe latte which looks amazing!

The lattes here are DIVINE and I always grab a plain croffle when I go. The baristas are super nice- I was intimidated the first time I walked in BUT they were kind and helpful and patient while I asked questions and decided what to order. The vibe is very calming and a great place to study or wind down. I took my friend and my fiancé and they both loved the lattes and pastries as well- it's become a routine place. I also feel like their prices are pretty decent for the quality.

Recently visited Grid Coffee in Diamond Bar and was thoroughly impressed! I ordered the Einspanner Iced Latte, and it's easily one of the best coffees I've tasted within a 15-mile radius--strong and sweet, just how I like it. The interior of Grid Coffee adds to the experience with its modern design and unique architectural seating. It's not only a fantastic spot for studying, thanks to plenty of outlets, but also a great place to relax and catch up with friends. The music volume is perfect, creating a pleasant ambiance without overwhelming conversation. I arrived late in the afternoon and found that most of their cookies and croffles were sold out, which just gives me another reason to return soon. Definitely making Grid Coffee my regular spot for a coffee fix!

Grid coffee is a city away from us but my hubby and I decided to drive and try their coffee. It was a rainy Saturday morning and i believe they just opened up. First impression of the place, minimalist to the point that the room looks kinda empty. The tables and chairs (if you can call them that) or benches look really uncomfortable and hard. I don't really mind because we were there for the coffee. I ordered the Spanish latte (not sure if this is the right name) but it was really good with cinnamon and just enough sweetness. My hubby ordered the blue lavender latte and that was really good too. All in all, it was worth the drive and will surely go back again.

Really excellent coffee and matcha drinks. Good service. Has non-traditional seating but still comfortable and spaced out well.

The place looks very nice and clean. Julianne made our drinks and they were perfect. She knew exactly how we wanted our drinks.

Tried out the Kyoto cold brew, Super strong literally felt heart palpitations...??? Open ceiling concept was not a vibe, it's giving chipotle respectfully. Cashier with lots of tattoos, attitude could've been better. Probably wouldn't visit again.

Loved the einspanner coffee I tried while visiting my friends in the area! The shop is clean and spacious with some unique seating for customers working remotely or studying.

Love, love this place. It's both a curse and a blessing that my work is so close because I have to stop myself from coming here everyday as soon as I'm off the clock. Favorite drinks are the Einspanner Latte and Matcha Cream Latte. What they both have in common is their delightfully indulgent and thick cream they layer on top of these drinks that elevate the drinks so much. Aside from not the most comfy seating which at least still add to the aesthetic, the vibes here are great for a good book and the music is always on point.

The vanilla latte was so yummy. Might be one of the best vanilla lattes I've tried. The syrup didn't overpower the drink at all and it wasn't too sweet either. The seating isn't ideal so I wouldn't go to get work done. The service was very nice and efficient.

It's alright. I got their strawberry milk and expected it to be balanced, but whoever made my drink added too much strawberry purée and it was too sweet. It took up at least 1/3 of the cup and the milk they used was really heavy for some reason, even though I got a nondairy milk. The space is big but it's difficult to sit on the wooden seats for a while. I wouldn't travel all the way here only if I was really close? And I was craving strawberry milk violently. Also someone there said the strawberry milk has caffeine? Not too sure what that means...

It’s 8 am: No one else is in here, the music is blasting, there are no chairs out, just platforms and stools. and after I’ve paid they tell me they don’t have any decaf beans. So this place is folks without any back problems and god forbid you have a heart murmur. Wanted to try local coffee shop, but there’s a reason it’s empty in the morning.

very stylish space. unusual and creative coffee shop. Interesting interior. lots of places to sit. The latte was a little bitter. Waffles for sale. the staff are young, positive and polite

Atmospheric coffee shop, unusual furniture and pleasant staff. The medium Latte seemed like a small cup. The coffee itself is 3.5-4 in my personal rating out of 5. It seemed a little bitter. But you should definitely come and try it for yourself. This is purely a personal opinion. The guys are great and prosperity to them!
