Bangkok has so much in offer that everyone would find something for themselves. The food is easy to find, it's literally everywhere and there's a big choice of dishes. You can go shopping to any centre of your choice, visit temples, parks, ladyboy cabarets and other performances. If you go around you'll get floating markets, more temples and rural life experience. Worth to visit at least for a few days but stay close to BTS as it's the easiest and most reliable mean of transport in the city.
