Interesting to see how your portion for the same plate gets smaller every single order. My family starts to getting massive... diarrhea from the last few visits, definitely won?t visit again. Read more

Friendly service. PadThai J has always been a favorite but this wasn't a pleasant experience. I was hungry so I continued on. I... spat out a piece of clear plastic from my water and the beef in my basil dish was tough and gave off a really weird smell, thenI found a yellow piece from the outer cover of an onion in the dish. I don't know what the deal was today, but this experiencewas disappointing and concerning. Salad tasted good. Chicken wings tasted good. Pad Thai J veggies were ok but some piecestasted like the veggies were old&rotting. Read more

Disappointing portion sizes!! Charged us full entree price ($12) for an order of veggies but it was just a small disappointing... side of veggies. If you can drive a few more miles to Lafayette, ?Amarin Thai Cuisine? goes above and beyond with their portionsizes! You?ll never be disappointed and will always have left overs. Me and my fiancé are very hesitant to return to RoyalSiam again even though they?re closer to our home due to their portion sizes. At least charge accordingly for the portion sizeseen in the picture we shared from our meal. Even our pad see ew was smaller portion sizes than we?re used to at other Thairestaurants. P.s. We both weigh 120 - 150 lbs and don?t require an unreasonable amount of food. You know it?s a small portionsize when you open your to-go order and can see the bottom of the container and you glance at it with question ?Really?!?? Read more
