For an international airport, very limited shops and restaurants that are open at evening hours, most closed by 7pm. Only Pizza Hut and KFC open with very limited 5 item menu. Very disappointed very long layover. Limited English speaking staff, poor security and immigration service, long lines and very confusing signs and no one stays in queue. Almost missed connection on short connection time. Update: March 2019 layover was much better than previous trip. Much more efficient with added electronic immigration check-ins. A few more restaurants and stores. Still most closed early.
