• 9/24/26The food was so good, one of the better thai places i've had the noodles weren't dry and veggies tasted fresh, portion was a good size, i called because there was no option for no peanuts for the pad thai and the woman on the phone was really sweet and made sure to write no peanuts on the order, definitely ordering here again :)

• 6/8/24thw pumpkin curry had large chunks of chicken and soft pumpkin. generous amounts of protein. the Pumpkin Curry had a relatively mild coconut flavor compared to other thai restaurants. portion was decent for one person but the next size up container would be nice with more broth (think ot came in a 16oz)

• 5/13/24Our favorite Thai restaurant in Rancho Cucamonga. We've tried the others and Thai Diamond tops them all. We really enjoy their Tom Kah (Coconut Soup) . Always loaded with chicken and mushrooms.
