I was in sales for many years and part of my job was to entertain or be entertained by various clients. There were many gourmet meals. Some great, some not. Now that I'm retired we go to mostly inexpensive but mostly healthy restaurants.
One of our favorite restaurants is Velvet Taco. You order at the counter and they call your name when the food is ready. Their tacos are made up of some of the best ingredients, it is like a gourmet dining experience.

That's good enough for me at this point in my life. A good casual Thai restaurant with good Red Curry Seafood and Pad Thai Noodles also fits the bill.
The one thing I will say about some of the more casual restaurants is that I find the more "hip" ones like Velvet Taco play really loud music, so much so that we have to yell to communicate. The finer restaurants typically don't.
