Jomtien is part of the Pattaya municipality. Any services there come from Pattaya. It is Jomtien beach, Pattaya.
Some people have the impression that it is upper scale to Pattaya central they like to make the point they are from Jomtien.
Ever cruise up and down the lower Sois of Jomtien? Some of the worst, filthy, rat infested, probably drug infested slums anywhere. Add, the vacant condo shells and now the one way road to nowhere never thought much of the place.
