After many dining disappointments in Dillon, we found Sparky's Garage. On a busy night, they seated us quickly, and the great service continued throughout the meal.
The decor is "early corner garage", with lots of colorful memorabilia, from gas pumps to oils cans - even the cutlery is wrapped in a (clean!) "shop rag". Lots to choose from on Sparky's menu, & the meals, and desserts, are large.
A bit pricey, but worth the extra pennies to experience the decor and friendly atmosphere.
We recommend Sparky's, and will definitely return.
