The service at Lilly's is really good. Tippy was our waitress, and she really does try her best. However, the food was just a-ok. Nothing special or worth remembering from this place. I've been to many Thai restaurants in Vegas, and Lilly's would probably rank as one of the lowest in terms of how good the food is. Pin Kaow, Archis and Komol are far by superior - by a long shot.
The panang was so-so, and the pad see ew was ok at best. They didn't ask what level of heat you preferred on any of their dishes which is strange for a thai restaurant. We ordered the Lilly's appetizer sampler, and it was $14.95 for 3 pieces of calamari (teeny tiny pieces), two whole egg rolls cut in half, two pieces of fried shrimp and 3 little dumplings about the size of a quarter.
The amount of food and the quality of the food you get compared to what you're spending is not worth it.
