Eating out is no problem at all in major cities where you can easily find good restaurants. It is advisable to eat in hotels in remote areas unless you have a reliable advice from your guide. You should avoid uncooked, partially cooked or reheated meat, fish and raw vegetable, especially when they have been left out exposed to dust and flies. Filtered and bottled water is usually available and safe.
Cameras, precious jewelleries, cash, passport should be deposited at hotel or taken care carefully while you are travelling by train or walking in the streets.
