Was User at Subway a mag?
The sandwiches are delicious, but I was a bit worried when I noticed that one of the cooks didn't change their gloves and was handling cash and the coffee machines while also working with the vegetable and meat boxes. This was quite off-putting. Also, a little suggestion: please make sure to clean the tables! View all feedback.

What Kahn Yamada dislikes about Subway:
I stopped for a quick sandwich in Keystone and found the selection to be limited to the essentials of a traditional Subway. You can expect options like a cold cut combo or turkey sandwich, but don't look for meatballs, buffalo wraps, or tuna. We ordered a chicken wrap, but the staff behind the counter appeared quite bewildered. It seemed like they were new summer hires still in training. View all feedback.

The hours show 11-3. They weren’t open the 2 times we came by.

Typically, fast food restaurants only earn 2 to 3 stars at best. However, this Subway really took me by surprise—it felt like they were preparing sandwiches the way they did 20 years ago. The chicken was fresh, and they didn’t skimp on the cheese, veggies, or dressing. They labeled all my sandwiches without me even asking. The place was clean and well-staffed, even during the busy Sturgis event when they had a lot of customers. Overall, I had a great experience with their takeout service.

This Subway location provides food quality that is standard for the chain. However, its close proximity to Mount Rushmore makes it very convenient. I would rate the food a 3, the service a 3, and the atmosphere a 3 as well.
