If you want to play table games with relatively low limits and good dealers, Harrah's is a good call. Other than that, Harrah's is pretty mediocre. With all the new and newly renovated hotels, Harrah's hasn't aged particularly well by comparison. There's no theme, and it's not ostentatious or fancy. 20 years ago it probably seemed really nice, but it just doesn't stand out anymore.
If you play blackjack make sure to look out for CJ, one of the best dealers I've ever had the pleasure of sitting with. CJ has worked in Vegas since the old gangster days and longer than Harrah's has been around. He brings years of experience, luck, and a sly grin to the table.
