I view this book as a complement to Bayless's other books: once you are comfortable with Mexican cuisine, this book is a big help when you want to show off your skills for a crowd. He and his wife Deann (co-authur of the book) deal with the logistics of centering a party with various Mexican themes, from a "Luxury Guacamole Bar Cocktail Party for 12" to a "Classic Mexican Mole Fiesta for 24." Included are drink recipes, salsas, guacamoles (the roasted garlic and orange guacamole in particular is excellent), as well as many main dishes and desserts. Included are a surprising number of vegetarian options, important so that those guests don't feel left out of the party. The recipes also scale down well, if you aren't feeding 100 guests. Winners are the enfrijoladas, the guacamoles (not your typical guacs, these!), the Cochito Chiapaneco (grilled pork roast), the Tacos de Arrachera al Carbón, and his twist on Enchiladas Suizas. I didn't care for the Queso Fundido al Tequila, but so far most of the recipes have ranged from pretty good to great.
If you are looking for an introduction to Mexican cooking from a beginner's standpoint, I'd suggest either "Mexico One Plate At A Time" (by Bayless), or "The Art of Mexican Cooking" by Diana Kennedy. Either of those will provide you with the solid fundamentals that you need before you can get the most out of Fiesta at Rick's.
Pros:
* Detailed party-planning timelines
* Mostly good to excellent recipes
* Easy to follow and understand instructions
Cons:
* A few "clunkers" in the recipes
* Not a good Mexican cooking intro: the recipes make more sense if you are already familiar with Mexican cooking
