    The coffee beans are so good that I keep coming back. The staff is always kind and welcoming. It's also a great spot to get work done. Plus, the aroma of freshly brewed coffee here is just delightful!

    I love their coffee! This one is in Mass hall market, so grab a meal and coffee at the same time and enjoy.

    This place is located inside Mess Hall. This place has a lot of parking and is validated for 2 hours. There are many seating options insides and outside. It is very nice for you and your friends to talk. The lost bean has many popular coffee options. Their matcha refresher was very light. If you are a big fan of sweet then I would suggest to add extra sweeteners. Even though I had syrup it was still similar to a 6/10 sweetness level at other places. I would like to see more unique drinks as there was not too many drinks that stood out to me.

    SF vanilla latte with alm. Milk ; great!

    Maybe you care what I say, maybe you don't Coffee desire strong enough, matter it won't Located in the Mess Hall Market space Eatery and bar, collective, cool place! Menu, options beyond the need SF vanilla latte with almond milk, great indeed Size, flavor, iced/hot, standard, or specialty Your palate, your choice, decision not for me Go, make the venture your own Chat with the cashier/barista, seating plenty for friends/family (un)known I definitely will be back for a pre-work morning trip Always seeking out a comforting coffee to sip Parking, fear not Hopefully you have a positive "lost" experience, not forgot Okay, I've influenced you enough A just try it, decision not tough xo - Op

    This place has good coffee, but so do many other coffee shops in OC. However, I like this place for 3 reasons: 1) Michelle is the best. When I'm getting coffee I feel like I'm catching up with a friend, not just ordering from a barista. 2) they brew organic coffee and have gluten free pastry options - which is a bonus from a health standpoint. 3) it's inside the Mess Hall @ FLIGHT (an upscale food court), so there's always plenty of seating, and good spots for lunch.

    I've tried two other locations aside from this one located inside the Mess Hall at the Flight complex and just can't quite get into their style of java. I ordered a vanilla latte and also got one of the chocolate chip cookies in their small display case. You can't just have a coffee without an accompaniment, right? Like the other locations, I couldn't detect a vanilla flavor. And the coffee just has a flavor I don't enjoy as much as other places. Is it the beans? Or do they slightly burn them while roasting? I'm just not sure and my coffee palate is not sophisticated enough to pinpoint why it doesn't please me. The cookie was fresh and soft with plenty of chocolate chips. It's obvious from other reviews that The Lost Bean brews coffee that a lot of people love. For me it's just A-OK.

    New location in the Mess Hall.

    Doesn't have the same vibe as a normal Lost Bean location, but the coffee and the food is still up to par. This stand or kiosk takes over a full comer in the Mess Hall in Tustin. It's has all the Lost Bean coffee staples; cold brew, lattes, and so on. They do have food but it's pretty limited. Mostly just pastries and pre-made quiches and sandwich wraps. This a great place to sip some coffee, get some work done or have an impromptu meeting. There's also plenty of seating both indoor and outdoor. Need that caffeine boost and don't want to wait in-line. The Lost Bean in the Tustin Mess Hall will get you in and out and on our way.

    I love everything about this coffee shop. Not only do they have coffee and tea, they also serve acai bowls and healthy juice drinks. I ordered the green goddess 16 oz. Which is $6.50. And of course, it has all the green goodies you would expect: kale, green apple, grapefruit, and pineapple. I would drink this everyday I could. I also think everything is organic. Another positive for the health conscious person like myself. Pesticides cause cancer y'all, just sayin'. I fully appreciate the quality their ingredients here.

    I love The Lost Bean, and am glad to see them thriving with three locations in Irvine/Tustin now. This one is located in the Mess Hall. I ordered the Nitro Cold Brew, and I was a little hesitant because I never tried it before, but the sweet girl said not to worry because if I didn't like it, she'd make me any other drink of my choice. Great service! I ended up really liking it, but appreciated the gesture. It's different than what I can make at home and so refreshing for a hot day. They also have green juices and açaí bowls, and other non-caffeinated options here for those who aren't in the coffee mood.

    My go to ppace for then liquid of life! Michelle is the shiz! She remembers my drink by heart and nails it every single time. If you are in the area and need a quick pick me up definitely swing by. You will not be disappointed

    Mocha Drink was flavorless, not worth $8 for the 24oz. He tried correcting it but it still was not good at all, had to throw it out.

We ordered the Banana Coffee, Ube Latte, and House Coffee, and all three were delicious. I'm not usually an iced coffee person, but these drinks completely changed my mind.

Even the House Coffee stood out with its well-balanced taste. The line may look intimidating, but it's definitely worth the wait. This is another spot that's earned a place on my list of favorites, and I'll definitely be back to try more of their menu.

There was a line out the door when I arrived, but don't let that scare you away. The team kept things moving quickly and efficiently. I ordered the Matcha Pandan with less sweet, and it was absolutely delicious! The pandan flavor pairs well with the earthy notes of the matcha. Honestly, I cannot even imagine how sweet it would be without modifying the sweetness level. As someone who prefers non dairy drinks, I was happy to hear from the girl taking my order that it's made with oat milk. That creamy oat milk combined with the matcha and pandan made the drink smooth. This one is definitely going to be my new go to order!

I also noticed a fire place and a Television outside. Aside from their great coffee and Tea menu, they offer daily pastries, refreshments, small bites and coffee bean bags to go. I had the Horchata Latté with oat milk (available hot or cold). It was really good. It is made with 2 shots of their signature espresso with a house-made horchata syrup or base, steamed or iced milk, and a dusting of cinnamon. You could taste the quality of the coffee. It was really good. The coffee was a little strong. The service was great and prices are average. I really enjoyed hanging out in their shop with friends. They have several locations.

They've got a self-ordering kiosk, or you can chat with someone at the register, which is what I did since I wanted some opinions on teas and coffee beans. They've got a pretty good selection of swag including loose leaf teas, various coffee beans, brewing gear, clothing, and other items. And they've got an RTE case too. Plenty of space inside and outside to sit, and the outside seating area has umbrellas, shade, and even a giant Jenga-style game. I asked for some recommendations for tea and was pretty let down. They only had 3 available, and 2 were ones I could find pretty much anywhere else (Earl Grey and...English Breakfast, I think?). I asked for any unique ones and they had a lavender one, which I ended up trying. It was okay, nothing special. Very floral. I also asked for recommendations for beans that are not too acidic and had the Darkside suggested because it's their darkest roast. I'm excited to grind it up and try it!

Drinkable but not worth coming back for. Last time I came in alone and had a Flat White that was terrible and I dumped it out. I did not have time to ask for another but I'm sure they would have remade it. Wall Writers is located in an office complex but in a good way. There is plenty of free parking and in the afternoon and on Saturdays you can park right at the entrance. The restroom is located in a separate building across the courtyard and watching people search for it can be mildly entertaining LOL It is a nice place to work with plenty of natural light and a wonderful patio for enjoying nice weather. I just wish the drinks were a little better. But because of the convenient location I will probably try it again. Maybe Ill try something iced?
