Did the private midnight food tour. Met our guide at the meeting point and she was already waiting for us, spoke great English, very nice and knowledgeable. Our tuk tuk was really cute, pink with lights and fun music. The food was great - we went to a number of "restaurants" we would never have tried on our own and all the food was delicious. Our guide took us to a little hidden rooftop overlooking the river and wat arun which was beautiful.
Also got to see the flower market and wat pho at night, which was beautiful and felt very exclusive. Definitely ate too much! Great tour all around.
