Around 10-15k / month. I go out to eat locally with the family 1-2 times / week in Banchang, Rayong. Choosing between Thai (seafood), Italian, Japanese, Vietnamese, etc.
Sometimes if it's a special occasion we'll book a table at a fine dining outlet in Pattaya or environs. We'd probably eat out a bit more if the missus didn't enjoy cooking at home most days. Fortunately, most of our favourite local restaurants here have seemingly survived the 'rona. ????
