Thanks, guys. Been jet lagged so I haven't been on here since I posted that. I think the cart thing steered at the yoke, just like a motorcycle. Food was excellent. It's a big city, so they have Chinese, Italian, German, etc., kinds of restaurants in addition to Thai food. I had what might have been the best Italian dinner of my life in Bangkok. It you liked the photos, grab a cup of coffee and watch the action at this scooter taxi stand...

Oh, one other thing...they are close to India, so they had a lot of Indian food, too. It was all good. I was amazed at how polite everyone was.
