Rita's Mexican Food is one of the west side's quiet gems, a long-running Mexican restaurant with refined airs and great service. It also happens to have some seriously good guacamole. Order it tableside, which at Rita's feels less like a trite menu cliché and more like a delicious indulgence. The whole avocados are sliced right in front of you, the meat of the fruit smashed against finely sliced onions and tomatoes, and seasoned to your liking. The chips are part of the equation, of course, and they are hot and perfectly crisp.
