Amazing food!!! Excellent service!!! Best Thai I've had in a very long time!!! It's a small restaurant but very clean and very nice atmosphere!!! read more

Awesome local spot for quick, yummy Thai food. The Silver Noodle Salad, Prik King, and Tom Yum soup are standard go-tos every time I eat here. Have not yet tried the macaroon ice cream sandwiches, but am slowly trying new things--it's just hard to break from the staple comfort foods! Service is consistent--I always have a friendly waitress and the manager (or owner) is a charming, kind man. If you have a little extra room, the watermelon boba drink is heaven. Take advantage of the frequent customer stamp card! read more

I've been coming here for over 2 years but I just realized I've never left a review. Let me start off by saying the food here is amazing and the portions are sizable. I usually order the lunch special and have enough left over to make another meal out of. Everything I've tried here (e.g. pad thai, sa-te, chicken curry, spare ribs) has been enjoyable and expertly seasoned. The fried rice is always delicious and the macaron ice creams are incredible. The customer service is always great and they never fail to greet you with a smile. I'm guessing this place is family-owned because the vibe here is very friendly and homey. If you are in the area, this place is a must-try! read more

This is the go to spot for me and my boyfriend. We love the food here. Love the curry, noodles, combination fried rice, soups, and more. Definitely worth trying read more

Food always taste great with BIG portions never a disappointment! Service with a smile.

My absolute favorite place to get boba!! I've been coming here once a month for the last two years or so and I have never once been disappointed with my order. I always get the strawberry boba and it's so yummy! They also have a rewards program for drinks. Buy 9(or ten, I can't remember) drinks and get the next drink free! I've gone through a few of them, that's how often I come here. The owner is simply one of the nicest men I've ever met. Always greeting me friendly and striking a conversation with me while we wait for my boba, it always makes my day with his lovely customer service. As well, the wait time for my boba is around 2-3 minutes, so it's rather speedy. I strongly suggest a strawberry boba and one of their ice cream macaroons when you stop by. They're my personal faves, you won't regret it! read more

The food and service are amazing! This is one of my favorite places to eat. Fresh and clean with friendly staff. The staff are always happy to see their regular customers. It's like eating with family. I highly recommend giving this place a try and becoming a regular. read more

This place is so YUMMY ! they are always nice and accommodating when they don't have something they compensate with Thai tea or boba !

This has to possibly be one of the worst restaurants in Glendora. I only ordered from this place because there was a rain storm and I was too lazy to drive. The one star is for the fact that they deliver. Oh but wait, it'll take AN HOUR! So after waiting an hour, I was pretty amped for this food. It finally comes and I open my pad thai and saw that it was barely seasoned but I thought hey, let's give it a try. That was my first mistake. Why did I ever try this. It was rice noodles with maybe a pinch of seasoning? The fried rice was white rice with some vegetables. The orange chicken was so so, but you could get the same thing at Panda Express and it taste better. I spent $50 here and I couldn't even finish it. Overall, don't go and save your money. read more

I heard this place from my friend, they told me that this place taste not good. But I still wanna try every Thai food spot. Then I came here with my family. They do have some good foods, but not so good, just so so. The price is a little high for those food. Unfortunately I found out there was a hair in their plate after we finish the meal, soooo disgusting. We told the server, not for anything but just as a remind. But what made us really disappointed was that she said it's very normal and asked us just take it out. She said that like she doesnt care, without any patience or any sense of feeling sorry. Also, we waited very very long time to get the service every time. We waived our hands but the servers were just ignoring us.（ It's not because there were too many people.) read more

My favorite dish is chicken curry with white rice, and these guys nail it every time! (Like 30 times in the last year.) Consistently delicious, the perfect temperature, and great spiciness. Keep doing what you're doing, Thai Diamond! read more

They have a friendly service, food is amazing and they were faster then others to get the food to us. All fresh and totally worth to come back to! read more

This is my favorite Thai restaurant in the valley, even though I haven't actually been inside the place yet. What I have done is ordered delivery food from them a couple of times. Easy peasy, do the order online from this very app, and in a very reasonable amount of time a very pleasant young man shows up with heavenly creamy chicken in coconut milk soup, perfect potstickers , premium pad thai and other alliterative treats. Prices are reasonable, too. read more

Quick service after a terrible experience with another restaurant. Decent food. Would try again and recommend to others!

Love this place. The food is great. Staff is friendly and funny. Their pad Thai is phenomenal and the pad see ew was decadent. The pineapple fried rice was out of this world. Would come again! read more

This place makes me want to cry I love it so much. I am a strict Vegan with food allergies. No meat, dairy, sugar or gluten. It had been a very long time since i was able to enjoy meal out with my family that was not brought in with Tupperware that I had first prepared at home. The owner of this restaurant created a meal for me that met all of my diet requirements and it is beyond amazing. The first time we spoke he listened intently and made a list of what I could and could not have and gave me options based on my taste preferences. The whole staff is so kind and they make you feel like family every time you walk in. I say every time we eat there that the gratitude I feel for a meal that tastes that amazing is how I wish every person felt when they ate out! Now they all know my special order by heart. Thank you Diamond Thai for giving me a place I can enjoy dinner out with my family that we absolutely all love. It means so much. read more

We love their food, everything always taste wonderful. Ordered for delivery and food arrived hot, and well packaged. Miss dining in but happy to still be able to order. read more

Delicious!!! This the only place to go when you're craving Thai food!!! Pineapple fried rice is bomb and always fresh! Pad see ew is for reals very tasty and before you complete your order add a yummy Thai tea on there read more

Really good quality food and decent size portions. I like to give my business to smaller restaurants during this time. I have eaten here several times and it never disappoints. read more

Amazing!!! The food is delicious and the customer service is outstanding! Loved the Yellow Chicken Curry and the Coconut Chicken soup. The owners are great and go above and beyond. We had an unfortunate incident occur with our delivery (which was out of the restaurant's control), and both Grub Hub and the restaurant worked together to fix it. Looking forward to our next visit or delivery! I would highly recommend this restaurant. read more

Thai Diamond is a great place to enjoy a family run business with simple, yummy food and a friendly staff. Each time I have been in the owner has come over to our table to personally thank us, ask about the quality of the food and simply give of his heart - who does that these days?! Amazing. My favorite dishes thus far are the Seafood Pad See Yew and the Duck curry. Also, the taro boba is delicious! Whenever I am in Glendora, this is my Thai stop. read more

The food quality was exceptional and the service is excellent. I would definitely come back!!!!

this is becoming one of our favorites. My wife and i go often now that we have moved nearby. The beef satay is the best I have ever had, and the soups are very good. Pad thai needs some work in my opinion, but others seem to like it. Owners and workers are very friendly and helpful. read more

Love this place, they have the best dinners and their appetizers are delicious. Some of my favorites dishes are the beef & chicken satay, the rice that is included is to die for. I suggest the pork egg roll appetizer, but you can't go wrong with the veggie egg roll if that is your preference. Last night my husband and I had the Thai rice with pork and beef, it was just enough for both of us. If you enjoy a good ice tea, I suggest the Thai tea, with or without boba. Hope if you try this place you enjoy it as much as I do. Happy Eats!! read more

Stumbled upon this gem. The food was excellent and the service was exceptional. Definitely worth the 60 mile venture.

I have been here maybe a dozen times over the last few years. I am not sure where all the 5 stars ratings are coming from. The atmosphere is really not all that great. The prices are on the high side because you really do not get a whole lot of food. I always leave still hungry unless I order extra rice or more than one dish. The place has some unique tasting food though. My wife is a big Thai food fan so we do come here on occasion. She really enjoys the curry dishes here while I am a fan of Sa-te dinner. read more

Great food , cheap and delicious.The food here taste like original taste from thailand if you like spicy you can get spicy what you want. I love it read more

Such an amazing place! I recommend the chicken pad see ew! Low key and super amazing food! Everyone working is always nice and I am always happy when I walk out the door! Love ordering extra to take home for later : ) read more

Yummy! Wow! This place is my favorite Thai place right now. The pad thai, beef and chicken sate, chicken with mushroom and baby corn, orange chicken... everything that I've had so far is flavorful and delicious. The meat is always so tender and falls apart. And the Boba. OH! The Boba. I don't like Boba, but I tried it again here and became instantly addicted. Everyone that I have mentioned this place to has come back to me with only positive feedback. read more

The service was amazing; extremely quick and efficient!! The food was excellent, as I ordered the seafood soup and chicken pad thai.

this place is awesome! speedy service, awesome food. I always use delivery and they are so fast! i recommend pad see ew and the thai tea is the best! i get the wonton soup on a cold day. i messed up and ordered from another thai place down the street! biggeast mistake should had stayed with thai diamond! never a bad experience! read more

Again I love this place! I just recently tried their rice and it's soooo delicious! Again the owner and employees are so kind. They are always smiling and always having a good time. I don't think these other reviews are real and they are coming from next door. Smh. Like really how are you going to yelp on this restaurant and harass these kind people? It's just sad to tell potential customers that this place isn't good. Take it from a real customer! This place is so so so good. read more

Each time I go here, the workers are so pleasant. I really appreciate that. Their yellow chicken curry is really good. A lot of places mess it up, but they have a great recipe. So yummy. Their Thai Iced Tea, Green Curry, Pad Thai and Wonton Soup are all really good. I am so happy that they are in Glendora. I miss all my Glendale and Pasadena Thai places! Chinda Thai, Tep Thai, Daisy Mint, City Thai, Saladang - these all had good yellow curry. Yum. read more

Pulled into this place because I was actually waiting for my friends Starbucks drinks orders. I saw on their window that they had Thai tea so I decided to go in and get myself one. I ended up ordering a Thai tea and fried rice. Both were amazing! The rice was so delicious!!! And to top it off the take out service was amazing. Very good customer service and great food. Highly recommended read more

Wow!! This place is yummy and DELIVERS!!! The chicken curry, pad see ew, chicken pad Thai and veggie rice was amazing! Clean flavors and great quality food! We will for sure be back again! read more

Really like this place. It's unfortunate this place doesn't get as much traffic. I guess the people of Glendora still needs more time to warm up to Thai dishes. Although it's really weird because there is a Thai place in Old Town Glendora and it's got lots of reviews here. Few of the things I keep coming back to this place: 1. Roast Duck Soup - really good and tasty. Although sometimes they run out of Chinese broccoli. 2. Pad Thai - this is their best dish and in comparing it with the other thai places I've been, it's way up there. Some Pad Thais look saggy after a day or 2. Theirs is still yummy the next day or so. 3. BBQ Chicken and BBQ Spareribs - the ribs is really tender and the chicken is cooked well. Some places you go to, you will see the inside of the chicken to be bloody which means they prob had it frozen and just grilled it when you ordered. Yuk!!! 4. Silver Noodle Soup - this is perfect for the rainy days. If you are feeling guilty with the cholesterol from the duck soup, then go for this much lighter but filling soup. 5. Pad See Ew - it's ok but I wish they'd put a little bit more sauce. It's consistently lacking in sauce which means they probably have it measured already per order. 6. Garlic Lover Tofu - love this dish especially when I don't feel like eating any meat for the day. It's not good for the next day though as the lettuce would become wilted already. 7. Chinese Broccoli with Crispy Pork - yum! You get a good balance of good protein and really nutritious vegetables. Their curry's are good too although the servings are too small even if you order ala carte. But definitely this place is a must try. The staff are very courteous too. read more

I have been all over looking for DRUKEN NOODLES / SPICY NOODLES and I found it here.... OMG the food was so DELICIOUS and full of flavor... I am so very pleased, can't wait to go back.... The Pad Thia shrimp noodle was also very good... Pad Thia has a sweet taste to it..my husband LOVED it... Great Place I recommend it if u are in search for a great THIA FOOD place..:) read more

Really good food and had really good fried rice. The orange chicken was good too. I would come back for sure

Some of the best food I have ever had. This place needs to be on your places to go list, and it will very quickly become a regular place to visit. Their orange chicken blows every other orange chicken out of the water. I have not tried anything on the item that I haven't loved yet. Go check it out ASAP! You won't regret it! read more

I love this place! The owner is super nice, food is always great, prices are decent, service is always friendly, it's very clean, & the place has an overall comfy feel to it. Would definitely recommend you stop in, there aren't enough Thai places in the area, especially not good ones! read more
