well, then just hop on bus and in short time you are in Kanchanaburi, where you can enjoy great food in night market next to train station each evening

though I would be sad missing my favorite night stall in street parallel north with KSR at the eastern corner next to 7-eleven in the evening (you can pick few toppings together with rice for very low price and very tasty, also northeast from 7-eleven always great banana pancakes), but there is also great restaurant in western part of same street, can be recognized by warning that you have to pay for outside drinks, that's proper restaurant with great curry
