Those seats look pretty nice, but if it were hot they would just be indoors. There’s several people in jackets and suit jackets, so I doubt it’s hot. It’s all shaded and probably a mild day. Personally, I love going to breweries, and I almost always choose to go places with outdoor seating and sit outside. It’s much nicer than sitting in a sealed box all the time to get outside and enjoy the environment when you can.
