First let me say that Bangkok is fabulous. I love the city, I love the people, I love the food. The only thing I don't really love is the heat. The street food scene is amazing. Fast, cheap, and so very tasty. You see all sorts of things. Pork leg that's been simmered so long the skin is meltingly soft, served with braised chard and a hard boiled egg, over rice. Pad Thai made individually for you in seconds as you watch. A line down the block waiting for the best yellow curry rice in Bangkok. A cart with half a dozen different kinds of fried bugs and truck drivers stopping in the street to pick up a bag of crispy fried whole frogs.
Yeah. That. We found this cart on the way to the big food market area, and had to try them. We got a bag, 10baht worth of fried bamboo worms (a kind of caterpillar/grub) and fried pupae of some kind (I think they're silkworms.) The flavor is sort of nutty, and the texture is just crunchy. The vendor puts the bugs in one of the ubiquitous plastic bags, then sprays soy sauce on them.
