Hot Girl Siam Square One is a malatang restaurant on the fifth floor of Siam Square One in Bangkok. You pick your own meat, vegetables, mushrooms, meatballs and ramen, pay by weight, and choose between soup malatang and stir-fried mala. After sitting down, you hand your ingredients to the staff and the cooking does not take long; the soup malatang comes in a basic version or a milk version. The indoor air conditioning is weak, so it gets hot during the meal.
