This is what we do with newbies: Take them to the Beer Garden, a time-honored restaurant - been around almost 100 years - hard to believe. Order beer, sangria, limonada, a paloma, or water. Don't order the margaritas - remember this is a Mexican restaurant. Order the guacamole prepared table side. You get to make your own guac by directing your server: how much onion, how much tomato, how much salt, how much hot. It's interactive and fun. You can let your guests do this, but you can offer guidance. Then order queso fundido (fondue), one with chorizo, one without. Then order a side of refried frijoles. Then keep the chips coming. This is more than enough to eat, and everyone leaves happy. In the meantime, you have the wonderful view, the people watching, and the total Mexican ambience/experience. Your guests won't be disappointed.
