Grid Coffee

Grid coffee roastery is very modern place to be! They have lounge seating which i think is unique and pretty cool to stay around and chat with your friend. I tried their Mojito Coffee and it was very good. There is small scent of mint which i really liked. I was very glad that Diamond bar finally got quality cafe! :)

This place is freaking cute, very chill. The drinks and pastries are great too.

easy to find, ample parking shared with other businesses, nice staff.

seating available inside with a few tables outside. i like the simple design and large sitting area with small tables for your drinks.

got the dalgona milk tea, on the sweet side especially when the caramel? pieces on top melt into the drink, bring some water or you can go home and add some milk, the drink is premade so the milk cannot be substituted

Solid coffee joint. The dalgona latte hits when honeycomb starts to melt. Overall though, not super blown away by this place. Was expecting a little something more.

Visited Grid Coffee for the first time yesterday morning and loved my experience at this coffee shop.

The exterior of the coffee shop looks very small, but as soon as you walk-in, it's a completely different world. It is very modern; with plenty of room to sit, and hang out with friends.
The menu is not very extensive, which is something we definitely love. We ordered the matcha latte, matcha caffe latte and dalgona caffe latte.

The dalgona caffe latte look very pretty. The drink is topped with crumbled biscuits that you mix into the drink and gives it a nice flavor.

My sister and I loved our matcha drinks; we are not afraid to say that this is the BEST MATCHA DRINK we've ever had. We've had matcha drinks from so many places and this is the best. If you are a fan of matcha (like we are) or if you have always wanted to try matcha but are scared to try it... you have to try it at Grid Coffee because it will change your world.

mojito good, mint flavor moderate
refined, minimal interior design

Would have given 5 stars, for a minimalist look coffee shop complete lack of customer service, no smiles, looks like off the grid, coffee was good

Artisan coffee unmatched in the local Diamond Bar area! They just opened up recently too!

Spacious place and good coffee to hang out with friends.

One of the best coffee shop with a very modern interior design. Loved it. Espresso was good.
