First in the list: Terminal 21!
It was located right away outside Sukhvumit MRT, and the magical thing about this place is that, everyone thought this malls is for high classies! But it is not! It is affordable and each floor is designed to mimic the culture of each country: Rome, Japan, San Francisco etc! Best thing: Toilet!
Coming out from the Siam MRT (also walking distance to Sukhvumit MRT), we have all the malls like Central World, Siam Paragon, Siam Center, Big C Supermarket, and plus point of them, they are literally connected and are walking distance to each other!
Monster literally needs to carry/drag me back to Tune Hotel when i have serious gastric and the sore feet (what a day!) D:
