I really love ramen and I know there are tons of options for japanese food / ramen in bangkok. I've tried a fair number of places. But so far my favorite is Tan Tan Men on Sukhimvit soi 33/1. I particularly like this place because the noodles are freshly made and broth is especially unctuous.
Despite my loyalty to Tan Tan Men, I am always curious to try new places. So I'd appreciate your suggestions for what you consider to be great ramen in Bangkok.
