Phone gap is doable then awesome.
I can create Menu includes categories (Salads, Main Course, Sweets, Drinks, etc.) and subcategories (Vegetables, Beef, Fish) and Subcategories (Beefsteak, Lamb chops, Buffalo With Ginger, etc.)
For each dish, the iMenu should explain the details and ingredients of the meal as well as the price. with multilingual functionality as you want English and Arabic.
I am also well efficient with designing and development.
Along with server side validations.
Let me know the application in detail or share if you have any wireframe ready for this, such that I can input my suggestions.
Would be awaited to hear & begin soon.
Thanks
