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 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

Ordered Catering. The owner delivered it himself. he was so nice. I ordered an hour and a half before my scheduled party time and he was on time. The food that I ordered were Phad Thai, bbq chicken, bbq spare ribs and pepper steak. My favorite amongst all the delicious food that I ordered was the pepper steak it was so yummy! Everything was tasty! I would definitely order from them again. highly recommended read more

Wanted to share our experience at Thai Bar BQ The food and service was excellent. If you like good Thai and pleasant surroundings you should give it a try. Oh you have to try the coconut sherbet 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

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

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

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.

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

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

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

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

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

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

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

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

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

Friendliest and most accommodating restaurant I've been to. I ordered my food for pick up before work and ended up hitting traffic. I couldn't pick it up until my next break so I let them know I'd be in between 5-6PM. Ended up reaching at around 7PM and they remade my food right as I walked in. I didn't even have to ask them to remake it. I had told them it's okay if it's cold it was my mistake for running late. Seriously the best customer service! (The food was fantastic too) read more

If you're looking for really good Thai food, this is the place! The food is authentic, very good home style flavor, and the atmosphere is fun and inviting. Our server was so sweet and attentive. We finished off our dinner with Macaron Ice Cream. Cappuccino and Green Tea are the best. This has become our new favorite place. read more

This is the best place ever. The food is always great and now they have the most wonderful deserts. The mango sorbet is great. Also, they have smoothies that are also excellent. The customer service is also top notch. I had ordered chicken pad Thai and asked for med spicy, for some reason it was so spicy I couldn't even eat it. I called the next day and they replaced it for free. Thank you! I love this place, the restaurant is beautiful and the people that work there are great and friendly. read more

I came here for lunch and tried the pad sew and the pad thai. i really liked the both of them! The lunch specials are pretty good too! it comes with soup, salad, and rice. i will definately be coming back. :) read more

not sure what the 4 stars are for? Thai food has become like Chinese food was in the 70s, changes for a bland American palate. Thai food, sadly has become a victim to this dumbing down of its complex, spicy nature. The food here was okay, mint chicken, ordered as "spicy" was not, the accompanying spice tray did not help. The thai iced tea comes premixed and it's all sugar very little coconut milk. I know it's hard to find authentic Thai food in the sleepy burbs, but there are better. The lunch specials with a generous tip will set u back 11-15 bucks, spend it at a more authentic place that gives you generous portions 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

Ordered for delivery, estimated delivery, 40-50 minutes, actual, 1 hour. Not the worst past the estimate. Ordered chicken pad thai, it was ok. Vegetable egg rolls, not very good at all, tasted like dirty veggies. And the BBQ chicken dinner. This comes with a half a chicken, two shrimp, and fried rice according to the description. Got two drumsticks and a thigh, one shrimp inside the rice. If I ordered a half a chicken you should be getting a breast, thigh, drumstick and a wing, 4 pieces. Instead, you give 3 smaller pieces and pass it off as a half a chicken? Send what your description is or change it. Luckily the chicken is tasty but bummed that you didn't even bring what was expected. Would like to give 2.5 stars for the misrepresentation, subpar egg rolls, and slow delivery. 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

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

Was delicious and ready when I got there. Love that I can order online. Will be back for sure.

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

Delivery service is fastest i've ever seen. Yellow curry is to write home about and pad thai and shrimp fried rice is always yummy and consistent. Thank goodness for an authentic and fast Thai food place !! read more
