Groceries near Krystal

We are staying at the Krystal in a one bdroom w/kitchen. We want to get groceries right away. Can anyone tell me where there is one close?

Across the main street from the Fiesta American(4-5 blocks south of the Krystal) is Gigante--a huge store with groceries and about anything else you need. Just several blocks north is a Walmart. I imagine it has groceries--never been in it.

Thanks for the help!

Walmart would be the closest to the Krystal. You could walk there.
