LukKaiThong Siam Paragon (Thai Royal Restaurant)

LukKaiThong Siam Paragon is a Thai royal cuisine restaurant on the 4th floor of Siam Center in Pathum Wan, Bangkok, serving dishes such as pad thai and tom yum goong. It also sells Pang Cha milk tea bingsu and Thai tea bingsu, and accommodates requests to omit lime and cilantro from the tom yum goong. Lines are long and food comes out slowly, so a meal takes time. Staff service is lacking.
