Going to my first browns game this Sunday, what should I know?

Me and my friends are coming down from Canada to catch this sundays game.Just was wondering what i should know In terms of: tailgating, how much it costs to bring your own car versus just walking to the lot, what good eats are at the stadium and as well around the stadium. My hotel is fairly close to there. Any good bars or clubs I should visit also? I'll look up stuff online but I like to hear what people on reddit have to say first.

Any feedback is much appreciated!
