Im visiting thailand and i would like to now how much it will cost to buy food in thailand….hotel and plane ticket not included…thanks

Depends on your style and Itinerary.
What you want to do and where you want to go ?
Thai food is cheap and travelling to tourist destinations is also cheap.
You can get decent accomadation from 500 Baht a night but you can get a room for as little as 300 baht a night.
Food can cost as little as 40 Baht a meal but budget for at least 300 baht a day on food- western resturants 500 – 1000 Baht a meal.
for good rates on hotels go to agoda.com
for cheap flights say to krabi or chiang mai go to airasia.com.
Phuket and samui are expensive places to visit.
if you were to give us an Idea of your budget what you want to do then people will give you more advice.
For ideas and information go to sawasdee.com ( gives everything you need to know about Thailand even transport timetables and prices.
If someone asked me who had never been to thailand before this question i would tell them budget for 5000 baht a day and you will be able to do everything you want to.
You could easily still have a good time on 3000 baht a day but you wont be doing so many trips.
Have a wonderful time in The land of smiles
