After meeting your private guide in Bangkok, your evening exploration starts with a visit to Wat Hua Lam Phong, a hidden temple in the heart of the city where you are welcome to make a donation to a cause that supports the less fortunate, if you wish; your guide can give you details.
Then head to the Patpong Night Market, located in Bangkok's red light district, and walk along the busy street with your guide; if you're up for it, you can practice your bargaining skills with local vendors. Head down a street known for its nightlife scene, and try some Thai street food in Silom, where you can take a seat at a sidewalk table for three snacks recommended by your guide.
Next, hop on a tuk-tuk for a ride to the last stop of your tour—a bar chosen by your guide. Admire a view of the city skyline, and enjoy a beer while talking more about Thailand with your guide. Your tour ends here.
