We have a large deck off the side of our house, but because our house it quite high there is almost always a breeze. I am grateful to have the deck, but the back or front garden get used more, depending on where the sun is. We have a table and 4 chairs set up, but have only had dinner outside once this summer. It would be nice to update the metal railing for a glass, but they are quite expensive.
As a side note, we live near the ocean and there seems always to be a cool breeze, even in summer, so we gravitate towards warmer less-windy spots.
