I advise you to visit the site on weekdays, it will be crowded on weekends. Dress warmly - it's cold upstairs. Do not forget a hat and sunglasses, so that nothing prevents you from enjoying the views of the mountains and from the mountains.
A beautiful place, but too popular among tourists. And loud music from cafes spoils the impression very much, but this is easily remedied if you walk 1 km in one direction or the other. That's where the real mountain silence is. Coffee in cafes, admittedly, is very good, so in general you can enjoy visiting. If you're lucky with the weather, of course. It can be very cloudy.
You should not count on a good view, the city of Almaty is likely to be closed by smog even in good weather.
There are cafes, and on weekends you can order pilaf in the yurt.
