Eating in hotels can be a bit boring because there are so many which serve acceptable food in a very formal atmosphere. The Riverside Cafe in Saigon where I went recently with my friends is great, quite expensive compared to other places but worth the money. There are lots of options to choose: salads, main courses and desserts are available from the international buffet. A soft drink and water are included.
