Another book I recommned is Berlitz's Russian in 60 minutes. The textbook is a small booklet only less than 30 pages. Easily portable by travelers, convenient for pointing out what one needs as all of the words are listed one side in Russian and the other in English.
Available in Caves Book Store and in Eslite Book Store
