Apparently all locations of the Mugs have been bought out and rebranded. The location in DB is now rebranded as Outpost Coffee. It appears that they are still in their transition phase as there are still signs of "the Mugs" throughout, including the same menu and company info poster. I got the Banana Caramel latte and it is so good! Slight sweet banana flavor but doesn't overpower the espresso so it still tastes like a coffee drink. Plenty of seating for working and just hanging out. Parking is plentiful, staff is nice, just wish the noise of the refrigerator case wasn't so loud so I could enjoy the background music. read more

Needed a place to get some work day and Outpost Coffee really came in clutch. There were plenty of parking available in a plaza which is shared with other businesses. I went on a weekday before noon and had no issues with finding a spot. For ordering, they had a kiosk inside with pictures for reference as well. It does accept American Express. After ordering, it only took a few minutes before it was ready. As for the atmosphere, there were a few other people, but they were mindful of noise. 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. However, after the hour, I reconnected and it refreshed the timer. For my coffee, I decided to get an iced Dalgona latte. They provided many pieces of Dalgona. I did ask to get this at regular sweetness and ice. Overall, after the Dalgona dissolved with the ice, it felt like a good amount of sweetness. It was decent, but I've come back to try other drinks! read more

Local coffee spot in DB that serves drinks and pastries. Stopped by with the purpose of dodging Starbucks and trying a local small business. Ordered a Spanish Latte iced and I was highly satisfied with the tastiness and quality of the drink. The staff was pleasant and super welcoming. The store is clean and appears to have a good amount of space for patrons. I'm glad I checked it out, and will definitely return. read more

The Mugs - Spanish Latte (iced). - Coffee & Tea Near Me - Diamond Bar, California

Parking is a bit difficult in this plaza. Free wifi available and plenty of seating, outlets available at the tables in the middle. I go to The Mugs once a week with my friend before class for a reason!! Baristas are kind and always helpful with drink suggestions and if you're not happy with your drink they will make adjustments. I love their espresso tonic especially with their homemade orange syrup! 10/10 always hits. My go to drink before was their blueberry matcha, always solid and consistently good. One of the few cafes I keep coming back to. read more

Stopped by on Saturday, 01/11/25 for the first time. I ordered the matcha latte (warm) which was a bit strong and wished it was a bit more on the sweet side. the matcha authentic taste was definitely there though. Great vibes, clean interiors, and lots of folks studying and/or on their laptops. A nice place to catch up with friends. read more

The Mugs - 01/11/25 - Coffee & Tea Near Me - Diamond Bar, California

Parking is all around the building. From the moment we entered, the barista was very welcoming and helpful. It's a cozy space and has a modern feel. We ordered a nutella croissant and iced earl grey tea. Both were good! It is a bit echo-y inside so I felt bad because a lot of people were studying but my friend and I just needed a space to catch up (sometimes we can be loud). I went to use the restroom and it was a maze to get there! It was pretty clean but just gotta walk down a long hall and use their code. read more

I have visited The Mugs several times throughout the years and have always enjoyed relaxing inside the warm atmosphere while enjoying their drinks. My favorites include the orange espresso tonic and berry hibiscus tea cocktail. This time, I went with their hot chocolate. It was a simple, soothing drink. The hot chocolate's sweetness was subtle, and the chocolate flavor was nice but not particularly notable. The steamed milk was much appreciated with adding additional sweetness and creaminess. While not my favorite drink here, it was a nice change of pace and a decent noncaffinated option. read more

The Mugs - Hot chocolate - Coffee & Tea Near Me - Diamond Bar, California

Baristas don't really acknowledge you when you are at the counter to order for several minutes. I should've done an online order because it would've been faster than just standing there. Not sure if it's a social anxiety thing for them- and I'm totally not trying to be a Karen about it. It's just plain awkward to lock eyes and then get ignored for 7 minutes straight? It's a weird vibe in there in general; service isn't the friendliest/maybe management sucks and it's wearing down the staff? Who knows? Lots of students studying so, not a lot of seating during peak hours. It's relatively quiet for a coffee shop. Music is not playing super loud. Some bench seating and a good amount of tables, if you do get here early to beat the crowds. I think in the beginning when they first opened, they were very coffee-centered and all about specialty beans; but nowadays they seem to focus on the sugary drinks. I tried to give them another chance but I think the quality does not really justify the price. But then again, this is Diamond Bar- not LA or OC; not a lot of great coffee shops in the area in general. The matcha isn't very high quality and my matcha latte was not very concentrated (tasted mostly like milk). Their strawberry purée is really tasty though. The drink was $7.66. I don't think it's worth the price. Then again, this is Diamond Bar- not much competition here. read more

The Mugs - Strawberry matcha latte tastes mostly like strawberry milk - Coffee & Tea Near Me - Diamond Bar, California

If you're obsessed with buttery croissants, dreamy lattes, and a cozy spot, The Mugs is calling your name! This cozy cafe has some serious pastry and coffee game, and I am here for it. I met a good friend here to catch up on a Saturday morning, and we had a wonderful time. We shared a Ham and Cheese Croffle, Nutella Croissant, and Everything Croissant to eat. I got the Cold Brew w/ Almond Milk, and my friend got a Head Over Heels Latte; it was a Valentine's Day Special. Let me tell you - their croissants are STUFFED. The Nutella Croissant was a stunning two-toned croissant packed with Nutella, just wow! Their Everything Croissant also had a generous portion of chive cream cheese and had that perfect fluffy cheese with that savory croissant wrapped around it. As of February, they have a $2 promo when you get a pastry and drink, just make sure to add that promo when you are using the kiosk to purchase. They had a seasonal drink menu so I am sure their staff have fun making these. Their drink menu is super fun so I am sure every guest loves that. The Mugs has a bright, airy space, filled with big windows that let in so much natural light - perfect for catching up with a friend or settling in for a study session with your headphones. The vibe is super relaxed and inviting. I also got my eye on the Dalgona Latte, Rose Matcha, and their Lychee Lime Refresher for my next time here. I'll definitely be back with my laptop and a sweet croffle next time! Final verdict: This place is mug-nificient - I'll definitely be back for another visit! read more

Found this spot through Yelp and went there on the weekend to read with a friend & it was cute. So so many students were studying there so it was packed for sure. The drinks were delicious and would definitely come back. It's a casual and cute little place and does have a good along of tables. We had their croffles and those were delicious. read more

This place wins in all 3 categories, the food/drinks, ambiance, and parking! Food: if you love croffles you must try this place! Starting at $8 they have the best croffles I have had so far in the 626. First of all the price beats the cafes in Koreatown and they are consistent with the quality of the croffle. They also have a wide variety of other desserts but my favorite is the croffle! I am also a big fan of their matcha series, the matcha is smooth and not too sweet. Ambiance: Plenty of seating with tables and countertops. Service is quick here with two self ordering kisoks. Typically see people studying here rather than chatting. It does tend to get crowded during peak afternoon hours FYI Parking: big parking lot with plenty of spaces! read more

Cold brews, hot brews or specialties were served here with a pleasant Welcoming Friendly Smile which made us feel at ease during visiting the area. Are you Hungry no problem! I had a mouth watering Breakfast egg mini brioche. We were fascinated with their exclusive Chorizo Siiii Chorizo pastry bite! Overall we had a Great Relaxing Morning!

I got the blueberry matcha, everything croissant, and chocolate croissant. The blueberry matcha wasn't that great because it was quite pulpy and the blueberry taste wasn't very strong. I'm not too knowledgable about matcha but my friend who got a matcha latte and my friend that's gone there before told me the matcha quality isn't great. But the croissants were sooooo delicious. They had it freshly toasted and the layers were so crispy and yummy. The interior was very nice and they maxxed out the spaces to sit so me and my friend found a corner to sit at. read more

I'm new to Walnuts and I'm glad I found this Cafe. Their baristas are friendly, lattes are various and yummy, plenty of seatings to get work done or study. It's a great place for meet ups and open hours are long (7am-10:30pm). Parking is kind of crowded despite the plenty spaces, lucky they have additional log underground, so you're good. Just take elevator up to the plaza! I've been to their other location at Irvine, which was also a great place to do work and study, so I'm so happy to find this location! PS: Orange Espresso Tonic reminds of a nice cocktail! read more

Visited here to do some homework and really enjoyed the ambiance as everyone there seemed to be working on something. It was super packed so I ended up finding a seat by this large window. The sun hit that window directly however so I was roasting for a bit. Once I got my drink it wasn't too bad. I ordered the Iced Strawberries n Cream Latte which was delicious and wasn't too sweet. It was a little noisier towards the end of the day which is understandable. Cool place! read more

Drink was ok but nothing like pictured or described.

The place has nice vibes but if you need the restroom, you're gonna have to walk through the gym at the other side of the building into a hallway. Order at the kiosk. read more

The Mugs - Iced Strawberries n Cream Latte - Coffee & Tea Near Me - Diamond Bar, California

1st time, and definitely not my last! GREAT 1st impression- beverages, service and ambiance! Ordered: 1. Strawberries & Cream Latte (Iced) & 2. Kyoto Cold Brew w/ Cold Foam. The Strawberries were sweet & not too tarty- they blended in very well with the espresso, actually. Generous portions of strawberry bits, blended in with the right amount of espresso drink and topped nicely with whipped cream & a fine strawberry syrup (that does not taste artificial). Presentation was nice too. As for the Kyoto Cold Brew w/ Cold Foam, perfect blend. Service was quick to prepare our drinks, professional and friendly. What more can you ask for? The cafe interior is beautiful too! Modern cafe vibe that is perfect for studying in groups, solo or meeting friends/acquaintances/family, etc. Charming vibe. I guess the only downside, which has nothing to do with the cafe, but more to do with the plaza (location) is: parking. It is a busy plaza. So, finding parking may be troublesome, but worth it!!! read more

The Mugs is a great place for anyone who has work to do--if you can get there before it fills up. Wifi is pretty fast and so is the service. The ambiance is nice with lots of natural light and there are plenty of plugs underneath the main center table if you need to charge your devices. There are a few corner tables for plug access, but you're better off at the main table if seats are available. I like getting their Dalgona coffee, which is made and served in-house only. Another favorite of mine is their Everything Croffle, which is basically a croffle with sweet cream cheese and everything bagel seasoning on it. I like the combo of salty and sweet that it provides. The drinks are on the pricier end ($6+ for most of them), but there's a good variety for coffee and non-coffee lovers alike. read more

The Mugs - Dalgona Latte and Everything Croffle - Coffee & Tea Near Me - Diamond Bar, California

Not bad! I tried the Dalgona Latte. I can taste the coffee--it's stronger than the cafe latte (I tried a sip). I really want to try the horchata latte and Spanish latte too! I'm glad that they have the option to adjust ice and sugar levels and make adjustments for the type of milk used. They said normal sugar is no sugar which I thought was interesting. The order took about 8 minutes. I ordered on their self-ordering screen. There were a lot of people around 1pm on a Saturday. It's very big and spacious inside, lots of seating and great for studying. Right by the entrance, they also have a shelf full of stickers, pins, prints, keychain, and other merchandise from local, small business artists which I love!! For these, you have to take to the cashier for purchasing. Definitely want to come back to try the other drinks! read more

My Go to study spot bc of the ambience! Staff are friendly too. Matcha- 0/10 . actually the worst matcha I've ever had might depend on the barista too but please don't get it. Im an avid matcha enjoyer so maybe I'm picky but the picture should speak for itself Cold brew with cold foam - 8/10. Really good. But it came to $9 to add the cold foam so it hurt my pockets for nothing special LOL. Ham and cheese croffle - 10/10 . Sooo yummy. 100% recc. Good size too. I'd say this is a steal for the price ($9 ish) Anyway, altho the drinks r just meh I'd recc if ur looking for a place to study. And maybe if u get a diff drink than me the experience will be much better LOL. I'll prolly update if I get diff drinks . read more

You order through a kiosk and we did have to wait a while but I think it was just busy hour. read more

B L U E B E R R Y M A T C H A A few people recommended this place to me, so I thought I'd give it a shot : ) As soon as my friend and I walked in, I was immediately intrigued by the atmosphere. It had an extremely clean and cozy vibe - an environment that would make for an excellent study spot! In addition, the workers were super friendly and helpful with listing drink options : ) *** BLUEBERRY MATCHA -- As I tried the first sip, I was a bit confused. It was not horrible by any means, but it tasted a bit "off." Let me explain: My standard is Cafe Dulce's iced blueberry matcha, which is creamy, refreshing and balanced in the matcha to blueberry ratio~ The Mugs's blueberry matcha had a taste that differed with each sip. I would say the blueberry and matcha flavors themselves were average, but what made it questionable were the blueberry chunks within it. The little pieces got stuck in my teeth which made me go BOOOOO lol ... While this place may not be stellar in serving blueberry matcha, I hear the regular matcha is solid. In addition, my friend got the banana caramel latte and felt it was delicious! In a nutshell, I would definitely recommend this place as a pleasant study spot for coffee lovers !!! read more

Background On Visit: Wanted to check out a new coffee shop and "The Mugs" was near where we were eating at. Restrooms: They don't have restrooms inside the shop, but you can access the restrooms in the plaza through the double doors, walk around the staircase, and at the end of the hallway, it'll be on your right. Make sure you ask for the code to get in. Wifi/Outlets: There is wifi and there are outlets available underneath the long table Credit Cards: They're accepted Location/Parking: Located in the same plaza (Golden Springs) as personal injury attorney, James Wang, office is at (if you're familiar with asian cafe's the place mats have his face on it. Great marketing tool!) Ambiance/Decor: Pretty cool ambiance with modern furnishings. Lighting can be a tad bit better. From my observation this place can be a great place to study/work and maybe socialize. Service: Service was alright. The staffer behind the register was friendly, but wasn't really informational about the coffee beans that they offered. Felt a bit obligated to stay, but stuck through our plan to get coffee. Coffee Of Choice: I ended up getting a pour over, but thought the coffee was just okay. read more

used to be the mugs, but now rebranded to outpost coffee. when I went they were completely changing all the chairs, and quite honestly made the experience so much better then the wooden chairs. it's is such a great study spot, with great music and a good amount of busy, never loud or obnoxious. The WiFi was amazing and reliable. The coffee itself was so good, I got the outpost which is their specialty coffee and it was yummy. I love the quality of the coffee, definitely something special the matcha however, was just okay ! nothing special about it, a bit too milky. read more

I'm not in the Diamond Bar area very often but I may have to come around more often to stop by The Mugs for their honey lavender latte. Man, that latte was soooo good! And I find that lavender lattes tend to be a hit or miss - this was a hit. Great flavor, not too sweet either! They also give you milk options which I really liked. I tried their strawberry croffle too! I love that the whipped cream was a strawberry cream. That little detail made the world of a difference. It looks like a very chill place to get some work done and/or study + the staff is super nice. I also noticed the shelf they had in the corner with little stickers, pins and keychains for sale. Maybe they're local artists or staff members work BUT I thought that was a really sweet touch. And they had some cool Valorant stickers & keychains (s/o to my fellow gamers). Will definitely come by more often to try more of the menu! Thanks The Mugs & crew! read more

I don't find myself in diamond bar that often but when I do, I like to try any cool and new coffee shops that maybe in the local area. Today I came across The Mugs coffee shop, which is located in a small plaza off of Sunset. They have an extensive menu with a lot of choices for coffees and teas. But since I am such a strawberry latte aficionado, I decided to try their iced strawberries and cream latte. it was pretty good and the standard drink comes with two shots which I didn't think were very strong so maybe I would add a third shot next time but it's also Monday morning and I need a lot of caffeine! Tons of parking outside and inside it's very spacious with lots of places to sit and study if that's your thing. The parking lot has a two hour parking limit, which is perfect. There's also restrooms located inside the building, and the barista is very friendly when I placed my order. Orders are placed on a kiosk online and then they will call or text you when your order is ready for pick up. Overall, as far as strawberry lattes go, I would write this a three out of five and if I'm ever in the area, I would come back to try the lavender lattes. read more

I recently stopped by to try this location. I had previously gone to one in the Tustin area and had a good experience. This location is so spacious. I came in early within the first hour of opening on a Saturday. I was pleasantly surprised to be the only person there as I was worried that it might be busy and I wouldn't be able to find a place to sit and get some work done. I asked the barista what her favorite warm drink was, and she recommended the Spanish latte. She said it was sweet but that she could adjust the sweetness for me. The drink came out perfect. I loved the ceramic mug that the drink was served in. It was a pretty cold morning, so the cup helped keep me warm. It was perfect. I also got a breakfast sandwich to eat and a chocolate and a blueberry croissant to take to my friends. The breakfast sandwich was good. It was light and fluffy. My friends enjoyed the croissants, particularly the chocolate croissant. They also sell pins, keychains, and other items to the right side of the store. They also have kiosks where you can place orders. I will definitely keep this coffee shop in mind when I need to get some work done in the early morning. read more

A group of friends decided to drink tea and coffee after a short and fun pickleball morning. So I ordered the Sakura latte with cream. Barista is friendly, you can order at register or thru the kiosk by the door. The latte is lacking flavor but presentation is top notch. And I came back next day to try the Ice Banana caramel latte. This time coffee flavor is overwhelmed by banana and caramel. The small tables are more suitable for 2 than 4. The cafe does offer WiFi, but bathroom you need password to go to one just inside the plaza. Overall the decor is welcoming and interior design is comfortable. They offer drink with bakery, it's like a Starbucks with personal touch. Their coffee is better than tea. A great place to hang out as it's not loud at all. read more

Coffee in Diamond Bar, California... We were searching our Yelp apps for a nearby place to hang out before the Yelp's Golden Hour Event on Sunday, 9-24-23. Jeff found "The Mugs," and we agreed to try it. The free shared parking was almost full because inside, every seat was taken by young people (probably students) on laptops. It felt like a library because everyone was quiet, focused, studying, and/or reading intently. It took a few minutes to order since the barista was very busy. The cashier politely told us that she'd be right with us. I looked at the Seasonal Menu and chose the Pumpkin Spice Latte. The cashier asked if I wanted it iced or hot. I wanted Latte art and got my hot drink in an unusual, tall ceramic cup with a cardboard sleeve and no handle. The glaze was inside of the cup and on the outer rim so that the base showed the beautiful, natural colors of the clay. The Pumpkin Spice Latte with oat milk was smooth (not too bitter) and just right (not too sweet)! It gave me a much needed afternoon boost! It's too bad that we had to sit outside in the afternoon sunlight. It was warm... especially while drinking a hot beverage... LOL! Note: The restroom is in the Plaza. Get the code for the door before you go! read more

The Mugs serves high quality coffee beans grown, sorted and prepared with care. There was not any information on their website and in their store about where their beans are purchased or grown. They make their coffee to order and roast their beans in small quantities. Although their coffee is made to order, the coffee was not served hot. They have a limited amount of pre-made baked items for sale. The baked items are not made to order including the Croffle which was not warmed up. They are known for their "Croffle" which is a hybrid of a croissant and waffle with several toppings available to choose from. This item was popularized in South Korea. There is plenty of seating and self serve areas for people to study and feel comfortable in. read more
