Is it a small mall food court eatery? Yes. Is it nonetheless delicious food? Overwhelming yes!
Although the Thai food they offer isn't as authentic as bonafide restaurants (the local sweet mango is my favorite), I make it a point to go to here whenever at the mall. They offer sriracha sauce to compliment meals and the staff is quite friendly. While not mind-blowing, when considering the context in which Ruby Thai stands it is very tasty food.
Protip: tip them a dollar in cash and they will give you a frequent customer card, six meals then a free one.
Protip #2: there is a $5 credit card minimum.
