biofuel is carbon-neutral. it might cause some particulate pollution, but if it's minimal enough for use in a restaurant dining area, then the environmental impact is probably negligible.
The occupational risk seems pretty high. I recall hearing that using a wood stove indoors to prepare 3 meals a day is equivalent to smoking two packs of cigarettes a day. People would be upset if their employer forced them to smoke two packs of cigarettes a day. For the customer that's in there for an hour or two, though, not a big deal.
that's true, I didn't think about that. a restaurant probably has better ventilation and better fuel than a crappy household wood stove, but even, say, half a pack per day is a lot.
Even if it wasn't, the benefits of the natural gas ban would be only minimally reduced due to small share of natural gas stove usage being in Korean BBQs.
bamboo grown sustainably and turned to charcoal for use wouldn't be introducing new c02 into the atmosphere. it would be carbon neutral. Its definitely better than natural gas which uses carbon that was sequestered millions of years ago
