I very much enjoy coming here and eating or ordering food to go. Their lunch specials are great the gentleman with the hat I believe is the owner is very kind and welcoming. I am giving a 4 stars for my last two visits. I had the same waitress help me and I was less than thrilled with our service. The first I sat down to eat with my family. We had to wait for our waitress and look for her to flag her down for refills. It looks like she can take on too many tables on her own when it is busy and service can be a bit slow. The second time I placed a to go order and ordered 2 Tom Yum soups with no mushrooms. When I got home both had mushrooms. I'm not one to take food back and complain to have the restaurant re-make the food, I simply just do not visit for a while until I'm ready to give the restaurant another go. But I definitely recommend their lunch specials. I always had great service during lunch and the soup that comes with the lunch special is delicious! read more

I was craving for some Thai food on the way home, and this place pop up with 4.5 stars on Yelp. Ordered tom yum chicken soup and Thai BBQ chicken. The BBQ chicken was pretty good, but I found a hair flowing on top of the soup. End up throw away everything. Maybe it's just my luck, but I will not repeat. Update 9/16/17 The owner of the restaurant had reached out through yelp. To my surprise, instead of offer apology or look for ways to satisfy a unhappy customer. He insulted me! Accepting criticism in a positive manner and use it to improve your business is a key part of being successful. I guess he doesn't see it this way. As a business practice read more

Thai Diamond BBQ - Thai Near Me - Glendora, California

Took a chance on this place when I was browsing for Thai food on an app. Ordered Ground Pork Egg Rolls, Spicy Rad Na, Papaya Salad, Pad Woon Sen, and Chicken Pad Thai. All the food came nicely packaged and omg, everything was SOO good! I think it's the best Thai food I've had in a long while. Unfortunately I don't live close by and can only order it when I am at my brother's house, which we have already made plans to order from Thai Diamond if I go over there tomorrow. read more

I judge all Thai restaurants by the quality of their curries. I ordered the green curry dish and the curry was watery and had no thickness or substance to it. It was like a soup instead of the rich curries I get in better Thai restaurants. Also I ordered it with chicken and there was hardly any chicken in it. I also ordered the eggplant dish and the eggplant was undercooked with the skin super chewy. I will not come back here as this was very subpar. read more

Really enjoyed my first time eating here. Service was quick and I felt cared for by the establishment. Love their BBQ spareribs. Will definitely come back for more! :) read more

Very nice spot and great authentic thai food you won't be able to find anywhere near Glendora, highly recommend!

Don't grub hub here. Manager was polite but not organized, and food was 30 minutes late and no communication. When I arrived to pick it up 10 minutes after grub hub ready window, it was "a couple Minutes" which turned into me waiting over 30 minutes. After 20 minutes had passed, I asked if the food would be out soon, hostess said a couple minutes- didn't actually check on anything. 5 more minutes I say, if it's not ready soon I need to leave, she finally gets the manager. I say I've been here for 25 minutes and food was ready over 30 minutes ago- Manager disappears to look for food for 5 more minutes and I told the hostess bye (who stares at me like I'm the crazy one) and I left. 5 more minutes later, he then calls us and says we can come back he'll offer 20% off...wtf? Also, the chick working the front is one of those b**** who smiles and acts friendly until you actually need her to be slightly helpful. Meaning she lied about time left on the order, didn't communicate as it wasn't coming out , and seemed annoyed when I started asking about where my food was rather than trying to check on status and give me my food....and realizing she's the one making me stand there for 25 minutes waiting and requesting updates on it. sad life sad service smh ..F for her read more

I'm Thai and I'm typically picky when it comes to eating out at Thai restaurants just because it's always a hit or a miss. The service was great but the food was... meh. My bother ordered the satay and it was chewy and was paired with rice. Satay normally will come with sticky rice or toast and pb sauce. I ordered the pad se ew and I always judge off of what type of broccoli they use. They used regular broccoli. I'll give the benefit of the the doubt because maybe they ran out of the Chinese broccoli. All it all the pad se ew was bland and oily. I wouldn't say I wouldn't come here. Maybe it was just an off day for them. read more

This place is so good. We like all our dishes. Kids friendly. Will definitely come back again read more

Everything is just amazing, the food the attention the atmosphere the parking ! Lol their Pad Thai makes me keep coming!

First time here. Fast and great service. Ordered the pork BBQ meal and angel wings. Place was clean and not too crowded.

The food here is great! Good customer service and nice, quiet ambience. This is definitely a gem hidden nears the hills of glendora.

Delicious tasty thai food, with good quality. And priced very reasonable. Good customer services

I'm truly impressed with the service and the food. I ordered for pickup and it was ready within 20 min. I was also offered a stamp card which I will definitely use. They even offered to help me to my car. The tai tea is ok. Taste the same as other places. I didn't get the boba. I have mix feelings with boba. I only get boba teas from ten ren or half and half. Too many bad Bobas out there. We got the panang curry. It's the perfect spiciness that I requested. Not to dull. Just the right amount of heat. The pineapple fried rice came with 2 shrimps and some chicken. I was expecting all pineapple. So kudos there. I love that they put cashews in there too. The last dish is a typical dish. The pad se ew. But we always get the one with the tofu. Everything was perfect. And not too greasy. The panang curry was our favorite. It was loaded with veggies and beef. I will definitely come back. read more

Amazing staff, amazing food, one of the best Milk Tea's in the area! I work around the area, and I go to this place at least once a week for their Lunch Special and their Milk Tea! Most of the time, I order the Chicken Pad Thai lunch special. It comes with a side salad, choice of rice and a great hot and sour soup. The soup is very flavorful as well as the Chicken Pad Thai. Highly recommend this place to anyone who is around the area. read more

Great place! Sa te taste wonderful with the peanut butter sauce, would definitely come again

Cashew nuts were missing from my order of Pineapple Fried Rice. They were the main reason I ordered it. Not appreciated Thai Diamond BBQ!

Favorite Thai spot for the moment Pad see ew and pad Thai is delicious and flavorful. Both are a little sweet, but not overwhelming.

The staff is friendly. The service is quick. And the food is delicious. Come and visit this place!

Have to stop in here on my "Thai craving" days... been here about 4-5 times now.This place is "A-OK" in my book. On the weekdays they have lunch specials at $5.95. It's right on Route 66 right before Lone Hill Ave, next to the Starbucks & across from the Zuzu Chicken. They also have a location in Rancho Cucamonga. read more

Lovely atmosphere, great food. I got combination fried rice, papaya salad, chicken pad Thai and Tom yum chicken soup, all very good.

The food was great, the amount of spice level for each dish was good. And the host was very nice. Will definitely come back here again. Thank you. read more

I work across the street so this place is a treasure when I'm craving curry! I usually order online for pickup and it's always on time, always fresh, always tasty! Definitely recommend the yellow curry lunch special and Thai tea combo. read more

So happy to have found Thai Diamond! I love the yellow curry, the chicken with mint leaves and the chicken soup. I also love the caramelized bananas and sticky rice! So good! My wife and I had a fave Thai place, but it's just been replaced with Thai Diamond. Our kids love it too - their fave is the beef skewers and pad thai. Great location too. Right next to a Starbucks for a coffee after dinner. Also, love they are participating in eGood.com and 3% of your bill goes to support a local charity. read more

I found Thai Diamond BBQ on yelp. I enjoy Thai food and I wanted a lunch combo item. Its located next to Starbucks across the street from McDonald's on Route 66. Its a small restaurant. Decorations were simple and clean. The employees were friendly and quickly asked if I wanted to eat there or get food to go. I decided to order their lunch special chicken noodle with fried rice, salad, and egg flower. The lunch portion is a perfect size and I had leftovers. The best part it only cost $8. Great deal. However, their lunch specials is M-F 11-3pm. Just a note. It took all of 5 minutes for my food to be prepared fresh. The chicken noodles were delicious. I enjoyed their fried rice. Overall, I enjoyed my lunch special and would come back. read more

Was looking for a vegetarian Thai spot to take my mom to. Although this is not a vegetarian restaurant, they accommodate on any dish to replace with tofu. We really enjoyed the food and that's saying a lot when it comes from my mom as she is quite picky. She's the it's "too salty", "too sweet", "too this or too that". She actually had no complaints surprisingly. We'll be back! read more

Great place to come enjoy good thai food. Food is spot on, service is really great and helpful in recommending items to try. Super close to my home and you can call ahead and order to go! Only down side is the boba drinks. I used to work at a boba shop and I know the difference boba. A little too dry on the drinks and super thick which makes it hard to enjoy the boba at the bottom of the cup. I would wish if they'd make it a little more watery since it's too thick to enjoy the boba. Over all , I do enjoy this place and will come back more often. read more
