The best restaurants serving Greek food in Waltham Forest London

We visited The Olive in January, having been in previous years and had delicious food. However this time, the experience was not great. A cold draft towards the back wall of the restaurant, even though we sat next to a heater. The starters were great. For the main, the side salads were nice, but the lamb and chicken thigh and breast kebabs were overcooked and rubbery to chew. The fresh mint tea was clearly made with unwashed mint leaves, as there was a visible layer of dirt like debris at the bottom of the cup. The restaurant offered a replacement, which we declined, but still did not take it off the bill. Overall not a good experience.
