For a chain it's a good casual decently priced burger place. I stopped in with two friends after a day prepping and painting walls and we had a nice time. Our server was friendly and quickly corrected any issues we had (mushrooms on the poutine when we asked for none, incorrect bill, dirty to-go boxes). One issue might be too many for some, but when you're with good company eating good food your mindset is more relaxed.
I got the Mad Love Burger $14.49 with coleslaw as my side. I enjoyed my food and love that you can get sides that aren't french fries plus the side is bottomless so if you want more you can get more. I also tried the poutine and it was decent, not spectacular, but if you're hungry it works just fine. My friends seemed to enjoy their food as well (a burger and mac & cheese).
There are several options for burgers in Rocky River, you can go the fast food route with places like McDonald's, or mom and pop like Bearden's, or more "fancy" like Flipside. I think Red Robin is a solid middle choice that appeals to everyone from families to people looking to get the most for their money to those who need something casual and reliable for dinner.
