There are a fair number of hole-in-the-wall/folding-tables-in-the-soi Thai restaurants/food stalls in the Silom Night Market area. As jpatokal warns, yam wun sen is a spicy dish even by Thai standards, but can be awfully good. It's a pleasure/pain type of thing - between bites a typical Thai conversation may go something like "Ouy...phet...phet...arroy...phet mak!" ("Ow...spicy...spicy...delicious...this is really spicy!")
