The heat level can be adjusted on most dishes. You can find a suitable menu for Thai Cafe on Zomato. My favorite is coconut chicken and the ginger dressing for the salad.

Uber eats might be able to deliver, but they don't. Totally worth the drive though

They definitely have dishes that are naturally gluten free because of the ingredients. Ask the server, they will make suggestions, then ask them to verify with the kitchen just to make sure.
