Please give me some feedback on my IELTS Writing Task 1. Thanks!

The table below shows the sales made by a coffee shop in an office building on a typical weekday.

The table compares the number of different items sold from a coffee shop located in an office building (coffee, tea, pastries, and sandwiches) during four intervals on a weekday.

Overall, coffee is the best-seller of the shop, compared to the marginal sales of the other drink. In addition, 7:30 – 10:30 is the busiest time of the day, with three out of four products recording the largest number sold.

From 7:30 to 10:30, while about three-quarters of items sold are coffee and pastries (265 and 275 units respectively), there are only 50 sandwiches served to customers. Between 10:30 and 14:30, the sales of sandwiches are four times as much as that of the previous time frame, and coffee remains the second popular, with 185 cups are sold. Meanwhile, both pastries and tea have less than 100 units sold, at 95 and 50 respectively.

The total sales of the other two intervals are a little lower. From 14:30 to 17:30, a majority of items sold are coffee and pastries, at an average of about 150 units each, almost double the other two items combined. Between 17:30 and 20:30, coffee is still the best-seller, at 200 cups, followed by 110 sandwiches.
