The restaurant is actually called Food 4 Thought, with the numeral in place of the word "for". There are two locations, the original, which is near the Phucome junction, and the new one which is on Bumrungrat Rd. Neither is in the Santhitham Circle area. The original is shown correctly on Google Maps. The new location does not appear to be on Google Maps, so might have closed.
I have never eaten at the new location. I have eaten many times over the years (including recently) at the original. I recommend it. Quite a large menu with well prepared and generously sized soups, salads, sandwiches, wraps etc. Excellent breakfast dishes. They have vegan food if desired. Prices are very reasonable. The menu is available on the internet if you look at it on Google.
