We went to Dennys in Vandalia, Il. today . 2/12/26. it was a great noon meal and very reasonably prices . We both had a meal on the (meals under 10 dollars) menu. I would recommend this Dennys as it was fast and friendly service, good food and reasonably priced unlike the Dennys at Effingham Illinois that is slower than snails.
Got my usual, Santa Fe sizzlin skillet, smallest portion I’ve ever seen. 2 small eggs over lapped it. No peppers or onions at all, just like 10 uncooked potato cubes and eggs. Absolutely horrible. Service was good, food 0/10
This is the best Dennys. The staff is great the food is great.
