Food here is excellent, but eating well involves some counterintuitive advice.
For one thing, there are few “undiscovered gems” along the roadways. It is just not a thing here, and several Sri Lanka residents have confirmed this to me (one person suggested there used to be lots of them, but they have faded). During my extensive road travels, I saw many many closed, empty, or otherwise deserted roadside restaurants. The open ones had few or no customers. So don’t put a lot of time into searching for them. You will do just fine eating at the obvious restaurants, including hotel restaura
Often breakfast is the best meal, as you can sample hoppers and string hoppers. If they will cook a hopper for you with an egg (and spices) inside, do that.
