The sunsets are beautiful. Show up about an hour in advance and find a spot to sit. Outdoor performers are at various points in the square--some of them are excellent, some not so, some keep asking for tips, some don't. Also, Mallory Square is surrounded by shopping and restaurants. Very easy to drop a boat-load of money and then, once you get home, regret all the stuff you bought!!
