We (the wife and I) have been to Tsivilis 23 times, (24 coming up)the OliveTree was one of the first Tavernas we tried, Dianna & Lakis (and Alexi)have made us part of the familly since over the years since that time. The food is excellent along with the service.
We have seen staff at the "O Tree" who moved on to their own businesses and every year they are replaced with another generation of the most courtious people you could wish to meet. We strongly recomend the "O Tree" to everybody visiting the Island!!
Last October the meal we had was dreadfull, the service almos as bad . Not a place to sample real Greek hospitality!!
The company to book Asspassia is "Thompson Warm & Friendly". An excellent choice we have been there many time, Yiorgo and Kiki are the best and their children are georgous.
