    Came in on a Thursday at 1pm. Most of the seating was taken and seems like thjs place is laptop friendly. The ambiance is more on the trendy side, with wooden but tasteful seating, art hanging on the walls and a unique chair in the corner for what seems to be a photo-op. I ordered the iced cream top hojicha latte and my drink was ready in less than 3 minutes. It was so fast, I'm not even sure if they make the mix hojicha powder on the spot or if it's pre-made. Regardless, the drink was tasty and well made. This ran me $7 ($8 if with oat milk) and tipping optional. Grid Coffee is one of the better coffee/matcha/hojicha spots in the Walnut/Diamond Bar/Pomona/Rowland Heights area

    Cookie butter latte
    Melody L.

    First time I came here I thought the latte I got was just ok. Wanted to try a different flavor and saw they had a cookie butter latte. I was pleasantly surprised at how good this tasted! The cookie butter foam was so good and matched perfectly with their coffee! This will be my new go to latte for a while!

    Just an update - yes, still so good! I love Grid! Such a good coffee shop in the IE COFFEE is top notch and matcha good too.

    Strawberry matcha with almond milk
    Serina T.

    This review is LONG OVERDUE! :) I've been coming here since December 2021 & it's hands down my favorite coffee shop in Diamond Bar. I'm a matcha person so I've only ever gotten their matcha, and if not just their strawberry hibiscus (no longer served), herbal tea, and strawberry milk. I love their selection of matcha: strawberry with chunks. One of the best I've had! Their blueberry matcha is pretty delicious also. The customer service is great. Everyone is kind and efficient. I'd say the baristas kind of keep to themselves though and aren't overly enthusiastic. But overall, still welcoming & nice! The atmosphere is simple with wood seating areas. I like it. However sitting for a long duration can be a little uncomfortable since there's not much back support, but luckily they have a basket with padded pillows to sit on. Recently they added tables along the corner nook area which is great! Aside from that they have little tray-like table tops to set your drinks on or laptops/books/etc; while working. There's also plenty of outlets which is a plus. Not to mention they always seem to have a good playlist goin' :) Oh! & they have outside seating as well underneath shaded umbrellas. My only complaint is it gets really hot in there during the hotter months. Especially since they're facing south and catch all the direct light early on in the day. Don't get me wrong, I love the natural lighting! It's just more prone to getting hotter & I'm not sure if they have A/C. I'm sure they probably do but it's never been exactly cold in there like most coffee shops, mainly room temperature. All in all Grid is a great spot! I highly recommend :)

    Can a coffee place in Diamond Bar be this good? Yes, and that place is Grid Coffee. The store's simple layout shines brightly with the bold flavors it offers. I love their lavender latte, and many of these tasty pastries pair perfectly with a nice morning cup of Joe. Yes yes, I will be back for sure!

    Hot Vanilla Latte to go with
    Miori I.

    On a cold, rainy day, I needed a caffeine fix near Mt. Sac and found Grid Coffee thanks to Yelp. The photos and menu sold me instantly! From the parking lot, I thought it was just a small spot with an order window, but inside it's surprisingly spacious with clean lines and a minimal, Japanese-inspired aesthetic; super inviting. I ordered my go-to hot vanilla latte and couldn't resist grabbing a brownie, too. The latte was excellent, not all lattes are created equal, and this one had strong, smoky espresso flavor without being overly sweet. It absolutely hit the spot. The brownie came as a neatly cut rectangle of chocolatey goodness, pleasing to both the eyes and the taste buds. The calm, welcoming vibe of the shop was made even better by the lo-fi soundtrack playing in the background, such a nice touch that really set the mood. All in all, Grid Coffee is a little gem for anyone in the area. Great drinks, tasty treats, and an atmosphere that just feels right. I'll definitely be back!

    My absolute favorite local cafe, and even more that, one of the best blueberry matcha lattes, with oat milk, I've ever had in the world. I'm always searching for something comparable but I've never found anything in the ballpark of this taste. They used to have chia seeds in their blueberry syrup too which I loved but it seems to be removed now based on my last three visits. There are still whole blueberries at the bottom. My mom's favorite is the strawberry matcha latte with oat milk. Anytime I'm in town, I will make it a point to come here and was recommended this spot and have been recommending it to others myself as well. Although I personally haven't gotten the coffee here, I've heard only good things. There was always people here anytime I visit, a testament to it actually being good. I highly recommend coming to Grid Coffee!

    A quaint little coffee shop that looks small from the outside but spacious inside. There is a couple of tables outdoor and ample indoor seats. The wooden benches are not the most comfortable for long-term seating. I get the vibe they're going for. It's hip and aesthetic with clean lines. The service was quick and friendly. The drinks were excellent. I had the Blue Lavender Matcha Latte and it was really good. It hit the spot. The Dalgona Caffe Latte was not only good but pleasing to the eyes as well. I also like the different flavored croffles. They are not hard or too flaky. They were delicious. I am glad it's local which makes it a place I can keep coming back to.

    Dropped into Grid Coffee while I was in the neighborhood. It was a cold, rainy day but the parking lot had plenty of spaces and the line moved quickly. Ordered a hot vanilla latte and a brownie for the road. Both hit the spot. Service was quick and polite. The cafe itself is large, welcoming, and has a relaxed vibe. Definitely a great place to warm up, hang out, or get some work done.

    Double Matcha Latte
    Michella P.

    I love their double matcha latte! It's not watered down and has a nice green color, unlike some other places. The sweetness balances the matcha nicely without overpowering it. If you're a matcha lover, I'd definitely recommend it. The service is great too. Everyone is very friendly.

    Cookie Butter Caffe Latte and Mojito Coffee
    Sophia H.

    From the outside, this coffee shop looked deceivingly small and narrow. However, we were greeted by a wide, open space and a high ceiling when we stepped in. The interior has a minimalistic, modern, and industrial design. I ordered the Cookie Butter Caffe Latte with soy milk, and I asked for less sweet. This drink was creamy and yummy, and I could really taste the cookie butter. I loved the cookie bits. Even at "less sweet," it was still sweet but not overly so. All in all, I enjoyed the drink.

    Dalgona Caffe Latte and Mocha Caffe Latte
    Regina L.

    A modern coffee shop with minimalist aesthetics serving up a variety of pastries and coffee. We came on a weekend afternoon and there was a small line which moved quickly. I decided to get the berry and matcha scone along with a Mocha Caffe Latte. I enjoyed the scone which was moist and flavorful, and the mocha caffe latte was refreshing on a warm day. The chocolate did have an artificial taste to it though which I wasn't a huge fan of. Service was standard. Inside seating is available in a stadium type of setting, as well as on the floor which was interesting as I have never seen a coffee shop with that type of seating. It didn't seem too conducive for studying or meeting up in large groups and seemed better suited for smaller groups. Grid Coffee is located in a strip mall with easy to find parking.

    Do they accept cash?

    They do not

    Is this a good place to study?

    Depends, if you have many books and need space, they only have one long table that could be most comfortable for that. I've seen a few people study there the times I've come and they've utilized the table. They have two other seating arrangements… Read more

    Hi, does this coffee place offers gift card?

    Yes, they do sell gift cards.

    Do they make their own coffee? If so, do they sell the beans at the store?

    Do they have outdoor seating for people with dogs or are dogs allowed?

    Yes they do! For both questions. I have brought my dog here several times.

    Does the matcha powder used have sugar in it?

    Yes, it does! They said it is pre-sweetened. I always order a strawberry matcha latte and you can choose to have less strawberry or matcha to make it less sweet.

    What is the einspanner?

    Viennese coffee with a lot of whipped cream on top. Typically drunk through the cream, without mixing.

For the pastries, it looked like a lot of the ones I was hoping from browsing online were not available. I ended up getting the biscoff cheesecake. It was on the sweeter side but it was very good. For the drink, I ended up getting the banana latte. Been on a streak of getting that lately so wanted to compare with other stores. I didn't get a lot of banana in the taste. At least it had an espresso shot for the caffeine fix and did not taste like the artificial banana. Nothing special there and stand out. For the interior, they had a few seating they primarily accommodated a few groups of four and two. I was able to grab a bench seat that had an outlet. However, there wasn't enough space for my laptop and the items I ordered. WiFi was available but it had a 90 minute limit. The store had a moderate noise level and stayed busy throughout the time that I was there. The service on the order was quick and they do bring it out to you. The store also has their own house espresso which was a medium dark roast. American Express is accepted as a payment option here. Overall, it was a decent work spot. If I come back, I'd prefer to try another drink and hope other pastries are available. Would recommend the biscoff cheesecake for those that want something sweet and the house coffee beans for those that like medium roasts.

It's different from your typical bagel shop, with a subtle Korean twist that makes everything feel unique. Even their plain bagel is incredible, with the perfect crisp on top.

The owners are incredibly kind and welcoming. Sometimes they even give out free pastries if you come at the right time, and they are always happy to help.
