Mushrooms (Salt Lake City)
The one place that pops into my mind is Liberty Heights Fresh. Corner of 13th S and 11th E. It's a tiny place, but Steve packs in lots of goodies. I love to go in there and just wander - I always end up buying more than what I came in there for!
If LHF doesn't have the mushrooms you want, they can probably point you in the direction of another place.
Its a last minute item and LH was my first thought. I am going there anyway in order to hopefully pick up a pint of Dr. Bobs Ice Cream.
I am visiting but always like to cook dinner for relatives while I am here so tonight is my night. If I can't find them fresh I might buy some dried and add some fresh other type shrooms along with it.
