    Rhost Coffee Beans
    Sarah C.

    7/24/2026 4 1/2 Stars First time here. Came here early afternoon. It was not busy with no lines, but the cafe's seats were nearly filled. FLAT WHITE It wasn't bad. Slightly sour, but fruity coffee. Overall, I enjoyed it. Good mouthfeel too. Good temperature, it wasn't too hot nor luke warm. MANGO MATCHA At first taste, it tasted more like guava. But it was indeed mango. But a fake mango flavor. The mango flavor was there, but could not taste the matcha. It wasn't bad, but I had better mango matchas elsewhere. CUSTOMER SERVICE It was okay. Not bad, but not great. Staff could smile more than just stare at you. Even say "Hello" or "Welcome" when you walk in the coffee shop. LOCATION Located in a small strip mall at Golden Springs Plaza. Parking is medium-sized for the amount of businesses here. I had no issues finding parking in front of the coffee shop, although more and more parking spots were being taken. AMBIANCE + SEATS The ambiance was relaxing. No loud music. Lots of people coming in and working on their laptops. Five small tables for two in the center. Along the wall there were bar seats for 19-20 people. There's a long communal table in the center for seats for 4-5 people. At the front and to the side, there were 3 tables for two. Outdoor tables for two right outside the cafe. Bathroom is outside of the cafe and you have to enter the other part of the building with a bathroom code to unlock. Will I visit again? Maybe if I'm in the area. But I'm in no rush to come back.

    Outpost Coffee is Diamond Bar's local coffee shop with delicious matcha and coffee. Ordering online is a breeze and my drinks are always made on time. The strawberry matcha has just the right amount of strawberry that you could taste but not overpower the matcha. Their spanish latte was smooth and tasted great. Can't wait to try more drinks.

    FIRST visit: * FARE(S) feasted on: *** Matcha latte *** Honey Oat latte *** Decaf oat latte * FRIENDLY service: Yes * FRESH air seating outside? No * FAIR pricing: Decent * FREE parking: Yes, plaza lot - note, entrance is before the street light and corner building * FYI: Delicious, fresh brewed (strong) coffee & friendly smiles for service - spacious, brightly-lit café for studying or getting work done (every table was occupied by someone working on their laptop on a weekend). A/C was strong on the day we visited, so bring a hoodie if you consider staying here for a while. FOUR & 1/2 stars **** '

    This location is nice and clean. The baristas are nice. Coffee is good and they have good summer specialty drinks!

    Pistachio outpost and Dirty Thai
    Simran K.

    Such a cute local coffee spot! I ordered their pistachio outpost and it was so good. I was afraid it would be overwhelming sweet so I got it with 1 pump of flavor instead of 3 and it was perfect. The bits of pistachio on top made it even better! Also ordered their dirty Thai and my bf really liked that one too. For food we had the avo bagel on the jalapeño cheese bagel and the turkey sandwich. Both were delicious! Will be back :)

    Banana Caramel Latte

    Stopped by this morning to try a new coffee shop and the atmosphere was welcoming and the staff were delightful. The coffee my wife had, she loved it and the refresher I had was tasty! Definitely can't wait for them to open up the new location near us!

    Earl grey latte (spring menu 2026)
    Francisco M.

    There's a plaza parking to get here. Inside is sleek and chill. Seems like a great place to meet with a friend or some studying. The staff are nice. The drinks arrived at a good pace. They have some tasty looking pastries that unfortunately I didn't get to try. I got the earl grey latte. The drinks was smaller than expected, especially for the price. I did get the earl grey flavor occasionally. There were hints of the lavender. It was enjoy enough and not too sweet. And it wasn't too hot so you can drink right away. I'd like to try more of the drinks.

    Banana Matcha
    Sabrina C.

    I came around 1pm on Saturday and immediately noticed how busy it was. Ordered:4/5 Banana matcha: the banana cream top works great with the matcha, however it did seem to be slightly overpowering. The matcha flavor was light but I would be curious to see how the other drinks taste! Vibe: This place is pretty packed with both people chatting and studying. It can be pretty loud, but with headphones, this is a good place to work. Theres plenty of tables but very limited on outlets. Parking: there's a parking lot shared in the plaza. However it can be pretty hard to find. Overall: this place isn't bad and I'm glad I gave it a try. It would be great for a quick catch up with friends.

    I had an adequate experience at Outpost Coffee (Diamond Bar). I ordered the Ube-Ube Coffee ($7). It's two shots of espresso with sweet ube. The initial sip is refreshing, but the coffee flavor quickly fades. As time passes, the drink tastes like sugary cereal milk. I arrived at Outpost Coffee (Diamond Bar) on Friday (around 11:48AM). The parking lot is big but busy. Fortunately, I quickly found a spot. The sign says, "2 Hour Parking Only - All Day." Staff is polite. Staff quickly took my order and answered my questions. My coffee took three minutes and 25 seconds. As mentioned, I ordered the Ube-Ube Coffee ($7). The caffeine is soft but uplifting. The drink is not bitter nor runny. However, the flavor of sugar and milk dominates the cup. It's not a memorable drink, but it's not bad. On ambiance, Outpost Coffee (Diamond Bar) felt a little worn down and old. The crevices were dusty and the location felt a little messy. There's about three electrical outlet. The location also has customer internet with password; details are posted on the counter. Fortunately, Outpost Coffee (Diamond Bar) has many clean tables. There's about six small interior tables, one long curved counter, and one very long table. The ceiling is tall, so the location didn't feel cramped. Overall, Outpost Coffee (Diamond Bar) is not bad. It feels shabbily maintained, but there's utility. If already nearby, I lightly recommend 4.2 out of 5

    Outpost latte
    Monica R.

    Stopped by on a Sunday morning and it was pretty busy, but the employees are very quick and attentive. I ordered 3 outpost latte and they were delicious. I got it half sweet with almond milk and it was a good balance of sweetness. The espresso was bold and smooth. There is plenty of seating and overall pretty chill vibes.

    Miranda J.

    Everything was sooo great! The employees were inviting and the place was super cute & just a great vibe! The mocha was delicious! We also were swooning over the jalapeño cheddar bagel. It was so good that we got a to go order before leaving of more food, coffee, AND matcha Just really enjoyed the overall service, thank goodness for good baristas 11/10 recommend this place!!

    Kat S.

    I believe this was the only place that truly offered a spring menu where you could actually taste the ingredients. I ordered the pistachio outpost, and it was absolutely delightful. It was so refreshing to enjoy the nuttiness of the pistachio. Service was good. I loved the large windows that let in all that natural light.

It didn't take long for us to get our coffee or our pastry. Their plain croffle was good, but I wished we had the option to have it warmed up. Their everything seasoned croffle was decent if you want a savory pastry. My banana cream latte was strong, but wasn't strong in banana flavoring. I mixed my cream too towards the bottom, and still found barely taste it. The baristas here are also very aesthetic and silly. They had a great time making coffee and taking orders. The art here is stunning. There's also plenty of study space with cushioning available. It's a lovely concept. I think I'll have to come back to try a different drink.

The music was also moderate, so I was able to focus without any earphones. There was plenty of seating from the center table to seating at the wall and even window seats. There were outlets available near seatings at the wall. There was also free WiFi as well. At first it indicated you would only have WiFi access for 1 hour.

We ended up ordering a tonic and a banana cold brew. They also had food items! We had chosen their breakfast burrito. Their coffee is strong and you can feel the caffeine. Yet, the sweetness is perfect and can mask your actual caffeine intake! It's amazing how they can do both. Their burrito was very savory and delicious as well. It's always quick and clean at this cafe. The baristas are always sweet. My fiancé and I do come here to do work, and their WiFi is decent, too.

    First time visitor Located in old town Pomona…read more Parking street side and parking lot - read signs in case cost Date solo family friendly group outing Some alcohol served and caffeine options Brunch and small bites Functional clean industrial decor with the lights and duct work Order In person as the toast app appears to charge slightly more Can be quiet and slightly loud but service was friendly Spanish latte very tasty just the right amount of sweetness efficient with timing of drink made Quesabirria tacos - 3 Slightly greasy but meat was tender and consommé was flavorful and tasty to dip freshly fried tater tots in Portion reasonable to pricing and photos of food resemble what was received Would return for a future visit
