I absolutely love Parker's Grille and Tavern! The most recent time I went there was last Friday. It was super busy, but we still got seated rather quickly and I can attest that during the entire dinner our service was spot-on and friendly.
In a small-ish town such as Avon Lake, the selection for beer and wine is absolutely ridiculous. Furthermore, the prices are incredibly reasonable considering the portion sizes and quality of the food. My brother had the Black-N-Blue Burger (with Cajun spice and blue cheese), which looked and *apparently* tasted delicious. I had the Pork Chops (16 oz. molasses and coffee spiked chop, and smashed reds), which I highly recommend!
In the end, I can't say enough good things about this place; you would be amiss to not go there at least once if you are a native to the Avon area. As stated in other Yelp posts, Parker's Grille and Tavern is a rare find for good American food.
