Habarana Village Tour includes lunch at a village and often only one dish isn’t vegan (fish from the lake).
There are many providers of similar tours and all appear to be similarly priced and the experience feels the same. Some tours start with a ride in a bullock cart, we suggest that you skip this. (You can decline and walk the first part, or ask them at the start and get a jeep ride to the first point of interest)
I also visited Tea Avenue in Colombo. If you want to know more experience, click here.
