@Mame,
1. I also read reviews of restaurants I'm not familiar with.
2. I read reviews of hotels and restaurants.
3. When I take trips or travel to other cities, I will always read reviews of various hotels and restaurants.
4. Along with other criteria, that helps me determine which hotel I will book.
5. Also, reading reviews helps me in creating a list of restaurants I might want to try out while traveling or visiting.
6. I just haven't personally written any reviews in a long time.
In some cases, I've booked restaurant reservations by phone, but never online.
When I read reviews, costs and prices are sometimes mentioned in the reviews.
