Learn Thai until you are fluent and speak like a local, then you'll get better reccommendations, not just tourist traps. Search for things in Thai and there will be more options, because a lot of local business are marketing towards local. Do your lessons regularly. What I like to do when exploring new parts of Thailand is asking the Grab driver what the good restaurants are in the area. Even if they get commission, the commissions are usually free food there, so it means that the food is good that they want to go back and have some too.
If you're not fluent yet, go to the park. Join a Tai Chi group or aerobics group. There will always be some buff aunties or uncles working out, enjoying their retirement. Those are the nicest old people you'll ever meet. They might look intimidating but buff old people are always happy. Chances are one of them know English and want to practice.
