In my opinion, Bangkok and Chiangmai are very alike. First, the temple of the Emerald Buddha in Bangkok and Doi Suthep in Chiangmai are both the popular places. Second, the local food, Although Bangkok and Chiangmai located in different region, you can easily find the same foods in there. For example Hang-le curry which is the local food of Chiangmai but you can also buy it in Bangkok. Finally, Bangkok and Chiangmai have the same transportation, such as international airport and railway station. However one thing that I think Bangkok is different from Chiangmai is a Lifestyle.
ou can buy it in Bangkok too.
