Aa Paa (อาปา) probably has the best noodles and meat I’ve had in Thailand. The meat is prepared to be so tender and delicious! However, getting to this restaurant is no small task, as it’s deep inside a soi (street). I think they have a Facebook page, according to the owner, but I have yet to find it.
But yes, the owner(s) of this place are really nice people. They came by often to say hi to us during our meals, to talk, chit chat about business/life etc. Very friendly place, delicious food, but super hard to get to. I doubt I’d be able to find it by myself.
