Tak is pretty dull when it comes to eating, with a few markets and the odd coffee shop the only attraction bar the noodle soup carts. Still, the quality of food is sufficient to survive and eating at these haunts may be a good way to interact with the local people.
The town hosts a morning market which is great for fruit, veg, fish and meat, but you'll struggle to fnd much pre-prepared or cooked foods; it's more of a wholesale affair. All around town are small kitchens serving noodle soups, fried rice or noodles, and local curries - the point and smile method is useful if you find it difficult to communicate with the locals, as not many speak English. The only non-local outfit we could locate was a branch of Hot-Pot Shabu, (similar to MK), just 20m from the entrance to the Viang Tak Riverside. If you're a picky eater then the best bet is to eat in the hotels; but don't expect any bargains.
In the evening a small but bustling night market sets up along the main road, beside the wooden bridge. Here you'll find nothing particularly special, but there's plenty of good fare like sausages, grilled fish and assorted curries from as little as 10B.
There does seem to be an abundance of small coffee shops and internet cafes, which generally have air-con; a good break from the humid temperatures outside.
