So… I guess when I think about the varieties of mushrooms that can generally be found growing in my areas - chanterelles and boletes are perhaps a better fit for things I make. I know where the pro foragers are going in our area, but even they don’t find tremendous quantities of morels… in our particular area, the season seems exceptionally brief. I get enough each year to toss them with some pasta, but the flavor is so mild and the body is so spongy that apart from “the thrill of the hunt” I’d be just as happy to substitute some other variety. I’d be very curious how you use them… I do find that if I dry them and use them to augment a soup broth, they add a nice umami.
They can be life changingly good, or not especially special. You need salt and dairy to bring out the flavor, but even then it's hit and miss. But yeah, in general they can be as flavorful as truffles, or as bland as button mushrooms.
If the average dish at that restaurant costs $40 or something, then maybe.
