This is the well-known BigC Store in Rajdamri in Bangkok. The store is a distance away from the BTS system and the closest stations are the BTS Siam station and the BTS Chitlom station. The British Embassy in Bangkok is not far from this Big C as well.
The Big C in Rajdamri is well located to many international hotels as well as the large Pratunam Market where thousands of people flock to each day to buy bulk clothing items. This is the biggest local hyper market in the areas where you’ll find every thing you need from dried dates and cheese! See the map below as you will note that the Big C in Rajdamri is also close to Central World in Bangkok.
