I've been here a total of two times. The first time was in the summer and they had an avocado Caprese salad on the menu. Delicious! My only complaint is that I asked for bread to go with my salad and was offered a sandwich bun.
The last time I went I ordered their Rocky River Burger. It was perfectly cooked but the burger itself was just "ok." It didn't seem like there was any seasoning or anything in the burger itself. The toppings on the burger definitely saved it. The fries were perfect.
If you go to Heck's and you're a coffee drinker, you MUST have a coffee while you're there. It's delicious and was the highlight of my meal during my second visit there.
