We came at 10:30a on a Saturday and were able to order and get our drinks very fast! The inside has a clean and modern look. Lots of tables inside and outside to sit at. The Pistachio Cloud matcha and Einspanner latte were both delicious! Will definitely be back to try some of their food. read more

Rien Coffee - menu as of 7/18/26 - Coffee & Tea Near Me - Orange, California

Matcha was good, but coffee tasted a little burnt. The prices for the drinks felt a little pricey for what they were, considering there were no milk adjustments or alterations. I understand coffee prices range upwards to $10/drink, but the drinks just felt a bit underwhelming for what they were. The inside has much more seating than I was expecting, so it is a great place to sit and chat, or bring a laptop and get some work done! Good location for this spot and hoping it'll improve a bit, as I know they recently opened. read more

Was happy to see a craft coffee & matcha spot pop up nearby so obviously gave Rien a visit. Visited on a Friday afternoon which wasn't a super busy time but did have some patrons filling the shop. It's a cute spot that has a lot of potential though I feel my first time was a bit subpar. I ordered an iced matcha latte and it was more milky than anything and especially at $8+ a drink, was tough to swallow. The barista who took my order wasn't friendly nor trying to engage beyond taking my order. These days, there's got to be more than just pushing out a drink considering there are tons of coffee / matcha shop options and said drinks are costing near $10. read more

Super cute vibes and interior. Love that they opened a cute aesthetic cafe in Orange! The iced Einspanner latte was SO GOOD. Going to try a regular latte next time. Food is super overpriced tho :/ I got the popcorn chicken and it was good but like $1 for each piece of chicken read more

The Einspänner latte is so good! It literally took me back to Europe. The cloud matcha latte was also really good. Definitely coming back! read more

Rien Coffee - Einspanner Latte & Matcha Cloud Matcha Latte - Coffee & Tea Near Me - Orange, California

I am gonna keep this review SHORT & SWEET..... The Double matcha latte was the BEST matcha I have had so far and I have had many matchas. The ambiance was sooooo cute, open and bright. They use agave as their sweetner which gave the drink a perfectly balanced sweetness. The service was friendly and helpful. ****** NOTE to the owner: Please buy one of those fly things for the store. I saw a fly inside the pastry container. I ended up not getting a pastry just because of that. I know it is not anybody's fault but you can reduce the risk of flies getting to the pastries if you put one of those fly repellent or whatever.... Bookmark it!!!! read more

Rien Coffee - The BEST double Matcha latte! RUN to this coffee shop and try it yourself!!!! - Coffee & Tea Near Me - Orange, California

With all the up and coming matcha spots, I am always trying to find a new spot to go to. Their cafe was cute with plenty of seating and also very aesthetic. I appreciate how put together their cafe was and menu options. Because each drink is made individually and not by whole batch, it takes 10-15 mins to get your drink especially if you get multiple matcha drinks in the order. Strawberry matcha 3.75/5 I appreciate the strawberry flavor and how cohesive the drink was. However, you don't get a lot of matcha flavor and volume for the price. Banana matcha 4/5 Good banana flavor especially because it tastes fresh and not artificial. Same notes of mellow matcha and can definitely finish in a quick sitting. Yuzu matcha tonic 3/5 If you've ever tried the honey citron tea mix at asian markets, this is what the yuzu tastes like. I was disappointed that they opted for this flavor instead of a fresh yuzu note. Matcha flavor was fine but the overall drink did not taste balanced and was more on the bitter side. If I am in a matcha mood and am limited on time, I would stop in again especially since it is close by. However, I think I'd choose another place to visit for more quality and price value. read more

Super cute new cafe in orange! 5 stars for the aesthetic, gorgeous indoor seating space, creative menu, and friendly staff. We ordered an iced flat white w oat milk & strawberry cloud matcha latte. I really enjoyed the single origin honduras espresso and the matcha was ok! i'm not a big fan of artificial strawberry flavor, so i wish their syrups were house-made. Hoping they get decaf beans and housemade syrup options soon! read more

Rien Coffee - iced flat white & strawberry cloud matcha - Coffee & Tea Near Me - Orange, California

New coffee shop in Orange/Tustin! While the place is very aesthetic, the food & drinks were rather disappointing for how much we paid. DRINKS: The double matcha was probably the best, but it was more of a light matcha with a dairy heavy cream top. The dirty strawberry soda was pretty bitter so my friend had to ask them to add sugar & it ended up tasting like a capri sun... FOOD: The avocado cream toast only had a hint of avocado since it was mixed into the cream with cottage cheese. I think a different bread other than sourdough would've been better. The kimchi grilled cheese was actually pretty good but definitely not worth $18. I'd only come back to do work if I need a quiet place since it's spacious and has several seating/outlets. Not worth the social media hype imo! read more

I really wanted to like this place but I got their matcha and it tasted literally like green milk. Had to go home and add more matcha in it to help it taste better since I didn't want to throw it away since I paid $8 for it. Not sure how their other drinks are. The interior vibes are cute though. read more

Inside is very well lit; big open space. Places to sit while you wait for your coffee or hang out. Ordered the hot hazelnut latte with oat milk; a little bitter aftertaste. It was good but not spectacular. A solid coffee. Sadly not a lot of variety in the flavors of latte. Also ordered the apple fritter, and it was soooo soft, warm and flaky. Soooo good! Coffee took a little while, although there was no one before us. A couple that came after us received their coffee first. read more

Cute spot for matcha and coffee with some sandwiches and pastries! They've got some tables but most of the seating are just chairs or benches, so this spot is best for hanging out instead of studying/working. Staff is friendly and capable. We enjoyed both their americano and blueberry matcha latte made with real blueberries. You can pay a little extra for plant milks and they've got cane sugar and simple syrup on the counter so that you can adjust your drinks. They have coffee and matcha slushies which are different from other spots I've seen! read more

Came in on a Friday around 8am. I'm reallllllly picky with my blueberry matchas and Rien nailed it! Service: 5/5!! Thank you to the sweet girl who helped us :) Drinks: 5/5 great iced americano (we got the medium roast in a 12oz), great blueberry matcha Ambiance: 5/5 good WFH space! Minimal outlets though!

Rien Coffee - Coffee & Tea Near Me - Orange, California

It was my first time trying Rien and the ambience is very mellow/modern which leaves room for lots of aesthetic pictures. The service was extremely fast. I ordered right when I got there with no line and within five minutes our drinks were finished. I got the Strawberry Cloud Matcha Latte and my partner got the Matcha Cloud Matcha Latte. The taste of the matcha was just right and it wasn't too sweet but didn't give me that "wow" factor. It's definitely worth trying this place, I'll be sure to enjoy their other drink options next time. read more

Stopped by here on my way to the park. Place was lovely, quiet and clean. Originally only planned on getting a coffee but ended up ordering the kimchi grilled cheese as well. So glad I did, it was so good! Staff were nice and service was pretty quick. Which is great with a toddler! read more

Rien Coffee - Kimchi Grilled Cheese Drink: Coconut Cloud Latte - Coffee & Tea Near Me - Orange, California

I saw this cute little coffee shop on Instagram and decided to give it a try. The drinks were good, but they felt a bit overpriced for the size. My daughter ordered the cinnamon roll, which was tasty, but it wasn't warmed up, making it a little hard for her to eat. Overall, it was a cute spot, and I'd probably give it another try. read more

Rien Coffee - Mango matcha & banana cloud matcha - Coffee & Tea Near Me - Orange, California

The space feels new and cool and the people are nice. The drinks are good as well. We got the strawberry cloud americano with their season dark roast, and the espresso is smooth with the strawberry foam not being too sweet. The matcha has a mango puree and is on the sweeter side. The mango puree can come on strong in some sips, but it is still a tasty drink. read more

I'm surprised with how many drink options/flavors and food that they had. The worker said the most popular matcha is the Banana Cloud Matcha, we didn't try that this time but maybe next time. The double matcha had a good matcha flavor to it, wasn't super strong and a good sweetness. The mango matcha was very sweet, it overpowered the matcha flavor a little. It does taste like real mango syrup. I saw them hand whisk the matcha and use agave as the sweetener. They have indoor and outdoor seating, super cute space. ig: @cravingswithcat read more

We stopped by Rien on Sunday to grab some drinks and pastries. The shop is adorable, and the staff are so nice!! The pastries were also very yummy. I got the classic cloud matcha latte, and my husband got the dirty coconut. We both really enjoyed our drinks, and the dirty coconut was especially good. I'll definitely try this again!! We got a croissant, vegetable quiche, and danish to bring back to my parents, and they were all tasty! But we thought they were quite expensive. We spent over $42, and paid more than $5 for a plain butter croissant, which feels pretty wild. The interior is super cute and very "clean girl aesthetic," and somewhat reminiscent of blue bottle. The staff were incredibly nice!! read more

Went in on a Monday Afternoon. The place is so beautiful made me feel relaxed! The customer service was great! I got an Iced Americano (single origin Honduras) The flavor notes were Cotton Candy, Strawberry and Honeycomb! It had a nice fruity taste to it very enjoyable! Definitely will be back to try more drinks read more

This place looks so cute and the matcha looked so good, and I was excited to try it. Unfortunately, they display two different iced cup sizes but can apparently only make a matcha in the smaller one? There was only one worker, so I waited in line just to find out I'd have to pay $8 for a tall matcha and they can't make it in the larger cup/size. I ended up leaving because I'm not paying $8 for a tiny small matcha. Such a bummer because it looked so good! read more

The best new coffee spot out there! If you're a bagel girly the bagels here are super good, the staff are all super knowledgeable and friendly. I got great advice on what type of espresso to get in my drink and I was super satisfied with my experience. The shop itself has really great vibes for studying or hanging out with your friends. I can't recommend it enough!! read more

Great drinks. They tasted awesome, got a flat white and a strawberry cold foam matcha. Beautiful bar and lobby set up. Service was great too, answered any questions and quick. Not sure if it was just an unlucky cup and lid match up, but I had some trouble putting the lid on even while trying to carefully do it all the way around like most places lids tend to, I almost collapsed the whole cup on accident. read more

I don't write a lot of reviews. This cafe not only CUTE looking BUT their pistachio cloud latte was so so delicious. I went two days in a row after my lagree class. I don't regret it. Second time I went I had to get another pistachio cloud & had to try out their kimchi grilled cheese sandwich with ham added. It was so good me and my friend shared it and we both loved the flavor. I have been to a lot of cafes this is probably one of my favorites this year. I can't wait to come back. Please open one in Cypress/Buena Park. read more

Vibes are calm in here, seating is a bit limited but good study spot. Much perfer this spot over Tru Bru any day!

Cute new spot! So many menu options to try. Got the hazelnut latte and it was delicious! Will be back again to try the matcha!

This place is really nice inside and clean, but the drinks were not good and the drinks took a really long time to come out. I ordered the blueberry matcha latte and coconut matcha cloud, and I dont know what they used (maybe a blueberry syrup) but it didnt taste like blueberries at all. I asked them to if they can make a new drink and ordered the matcha cloud matcha latte. They were very nice about remaking the drink, but it also took longer to remake the drink. The coconut water in the coconut matcha cloud was very sour, and the coconut cream did not taste like matcha at all. Everything here is just for the aesthetic, but the drinks were disappointing. read more

Needed new coffee shop in the area! The interior is super well-lit and decor is nice and welcoming. Unfortunately, I am not a huge fan of their coffee especially for the price point. I've tried their 12 oz vanilla latte and it rang me over $7 with no modifications or milk substitution.. I get a 16oz vanilla latte and my regular coffee shop for $5.50 so the price for what I'm getting here is a little too high for me. Nice shop to check out but I don't think it'll be a spot I visit often. read more

Ordered the banana cloud matcha, which was okay but the banana cloud overpowered the matcha. Maybe the banana to matcha drink proportions are better for the large, but for the regular size it mainly tasted like the banana cloud. The kimchi fried rice portion was tiny for $17.50 and didn't have anything other than white rice and kimchi with a sprinkle of green onion. Disappointing and likely won't return. Interior is beautiful though. read more

This new coffee shop definitely hits the spot. Yes, their drinks are a bit pricey, but worth the money. We tried the coconut cloud latte and loved it. The espresso flavor was bold and prominent, but was balanced nicely by the milk and coconut flavor once the drink was mixed. The staff was friendly and helpful. The decor is minimalist industrial chic, but there was enough seating for guests, along with a few tables outside. read more

The matcha was absolutely delicious, we got the strawberry cloud matcha latte and the mango matcha latte! They were both equally good. Arrived around noon on a Sunday and there was no line, got served right away and only waited a few minutes for our drinks. The coffee shop was also very cute and aesthetically pleasing. The drinks only come in one size and were gone in just a few sips... Wish they were a little bit bigger for the price. read more
