Looking for great places in Bangkok where i can find the best thai food (so no tourist places, but places where i can find the Thai themself. No chic restaurants, but great authentic spots! Area; democracy monument, or up north in Bangkok.
1. Why would you assume that if tourists go there, it's neither authentic nor good? I believe this to be a false assumption. I know of a VERY GOOD, VERY Authentic Thai restaraunt in Sukhimvite on Soi 22 which caters to tourists as well as Thais. My wife loves it - she's Thai. There's something to be said for "chic", but if you are looking to experience what your average, working class Thai does - that's easy...
2. You can find authentic Thai food on just about every street and near every shopping area in Bangkok. If you want to eat what the average Thai guy is eating every day (hence authentic), just go to a noodle stand or some dingy, hole in the wall place. There's literally hundreds of thousands of them dotting Thailand. God knows I've eaten at enough of them.
near Democracy monument:
it's one of my favourite areas in BKK cos i can combine sightseeing + food when bringing friends who haven't been to BKK before around. many of the little lanes branching off from the main road have a lot of character & walking along them & the smaller canals is a good quiet break from BKK traffic. just note that the above guide doesn't cover everything, so keep your eyes + nose on the alert along the route. & strictly speaking, some of the stuff in the above guide is Teochew Chinese food introduced by Thai-Chinese, rather than Thai food per se.
also see their link on Or Tor Kor market since that is in northern BKK (next to Chatuchak).
markets are a good place too - one not far from Democracy monument is Nang Loeng market along Nakhon Sawan Rd:
