Gregg’s substation feels like a Sioux Falls secret. It’s not real flashy or commercial looking, so you know they like to just focus on good food and good service. I ordered the Royal Combo sub, it had salami, ham, turkey, roast beef, pastrami, corned beef and provolone on it. Talk about a lot of meat, and it’s all cut fresh right in front of you. I got the standard dress and added fresh mushrooms (SWEET!) with sliced pickles. Their chicken tortilla soup served with fritos was the perfect side that had just enough spice to make it interesting. It was all awesome and just what you’d expect for a good hearty soup and sandwich.
