I've been a bartender for 5 years, and Mr. Boston has always been my first pick when I forget the recipes for certain drinks. I'm not sure why the other reviewers have such a problem finding drink recipes - Hot Toddies, as one reviewer searched for, is listed under 'Hot Drinks' on page 204-207 of the 65th edition. As for another reviewer, a Vodka Martini is just a Gin Martini with vodka swapped for gin, so perhaps the folks at Mr. Boston thought you might be able to figure that one out?
Yes, the book has a bit of outdated info when introducing each spirit, but the main point of the book is to have a solid reference for whatever drink someone may ask for, not to introduce the novice to the ABCs of alcohol. Drink recipes vary from coast to coast, but Mr. Boston is a great resource for the traditional and common recipes of many, many drinks. Keep in mind that this particular edition I'm reviewing doesn't have more modern drinks, like 'Monkey's Lunch' and the like. Perhaps the newer Platinum Edition is more up to date?
In short, if you're looking for an introductory book to bartending, get Bartending for Dummies or something similar. If you want a great recipe book that you can use for reference when mixing drinks, Mr. Boston is highly recommended.
