Roisen Pad Thai is a small Thai restaurant on Sukhumvit 71 in Bangkok that serves pad thai, Thai noodles, and som tam. The menu includes shrimp pad thai, phat kaphrao moo sap, and a thick tom yum broth, served with fish sauce on the side. The interior has air conditioning and is kept clean, which makes it comfortable for a meal on hot days. The food is not sweet, while the som tam and phat kaphrao moo sap are described as slightly sweet, so sweetness varies by dish.
