Here is place with live Thai music, dances and shows. Have a look, not sure if it fits the bill for what you want. http://www.tawandang.co.th/ http://www.tripadvisor.com/Restaurant_Review-g293916-d1888866-Reviews-Tawandang_German_Brewery-Bangkok.html

This happens with some frequency in Japan. I myself prefer to see a good 'sharking' over a wank and run.

Technically, yes. You are coming for business not tourism so of course you need that class of visa. Does anyone do that for the situation you describe? Probably very few. Many people live and work full time in Thailand on just a tourist visa, albeit illegally. For your situation it isn't going to raise any flags or seem suspicious at all.

You can check if this applies to NZ, but for US passport holders you get 30 days on arrival visa waiver if you arrive by air rather than land (you don't have to apply in advance). You can then go to the immigration office on day 28-30 and pay 1900BT for a 7 day extension. This would get you your 35 needed days without leaving or overstaying.
