Cordova/Phonegap best and most efficient way to store a lot of data?

I am working on a cordova/phonegap android and ios application. I am using the latest versions of cordova and jquery mobile. I am currently using sqlite3 to store data. Basically I need to know the best way and also the most efficient way to store hundreds of values. The way it is, I need to store roughly 100 city names, and for each city, I need to store 5-10 restaurant names and some of their menu items as well. So... in total im going to have upwards of 500 values, some being properties of others... making sqlite not the most practical storage method. PLEASE ANY SUGGESTIONS/HELP ? THANK YOU SO MUCH IN ADVANCE.
