visiting!

hello! i am thinking of visiting cleveland for my birthday with my bf and were wondering what some of best places there are to visit! we are looking to maybe go on a trail and look at some attractions and most all, i would love suggestions on a place for dinner that i can wear a nice dress and heels at and not stand out too much! where im from we mostly have bars and grills and im looking for a more fine dining setting. Thank you so much!!!!
