The Italian Underground is a small establishment in the basement of a building near the walking bridge over the Colorado River. So it is very conveniently located to the hotels near the Hot Springs Pool.
I repeat, it is small. So expect to wait for your dinner because it's good and they do not take reservations. As a group of 7 our wait was a little shorter than for some of the couples and groups of 4. It is VERY intimate.
The hot bread they serve while you wait for your food is excellent. Great elasticity and a good crust. I wouldn't describe it as a crusty bread, though. Lots of very good garlic butter is served with it in tiny ramekins. They featured three specials at dinner. While several in my party ordered one of them, I ordered Linguini with Clam Sauce from the menu. It was so good. There was a perfect amount of fresh parsley chopped into the dish, the clams were so meaty (not at all chewy) and there was PLENTY of garlic in it... Chunks of it... Mmmmmm. The salad included with the entree came with a choice of three in house dressings: Thousand Island, Blue Cheese and Italian. I chose the Blue Cheese and it was delightful. So many times, Blue Cheese dressings have a definite bite. This one was smooth and creamy. Spumoni or Raspberry Sherbet were the included dessert choices to top off the meal. I don't think anyone in my party was disappointed with their meal.
If I were to share ANY negative, it would be that they do not serve fresh grated Parmesan with the entree. One small thing...
