One of the busiest streets in Kutaisi but there are many places to visit - bunch of cafes, bakeries and restaurants. The Avenue is spacious with many trees on the sides and it's nice to walk in the shade during a warm day.
Very touristic city. Foreigners flood the place and locals get good income out of it. You can bargain everywhere as usually you can get to even 40% of the starting price with no hassle. Siem Reap is a base for visiting Angkor Wat temples which are roughly 10km up north. After a day of sightseeing there people come back to town to party at Pub Street, eat at Night Market or just shopping around, having feet massage and spa.
If you want a beach, go to Sihanoukville, there are plenty! You can choose from touristic and empty ones, small and big. Good place to relax after sightseeing other parts of Cambodia.
There's quite a lot to do at Silom area. You can find there shops and many restaurants with various foods. Shopping wouldn't be the cheapest but you might find interesting pieces.
