@willkmis the name of it is pretty clearly "California cuisine", the Wikipedia article is titled that and the restaurants say it like that on their websites. So I think that's what the tag should be. IMO it's less important that the cuisine titles all look the same and more important that they actually describe the cuisine and that future mappers will use the same spelling.

I did the mongolian grill work. At the end, my changeset had 156 mongolian_grill restaurants and only 3 true mongolian cuisine restaurants. This was for US+Canada.

I didn't know about the difference between California and Californian cuisine. You're right that they should be tagged separately. This affects 26 restaurants in the US (40 worldwide), that are currently tagged with california or californian. I checked the 16 US restaurants with websites, and 7 of them did say "california cuisine", but four of those were originally "cuisine=californian" and not changed in this changeset. I set those seven to california in osm.org/changeset/131741561. Going over the other restaurants or finding more restaurants to tag would require more work, but could be worth it if you want to promote cuisine=california as a recommended tag.

I also did not realize Mongolian barbecue is not actually Mongolian. However, it seems I am not the only one. Before my cleanup started, there were 183 uses of "mongolian" and only 15 uses of "mongolian_bbq" plus a few with other spellings. Most of the restaurants currently tagged mongolian, at least in the US, seem to actually serve Mongolian barbecue. Given the number of uses of the tag and the fact that these restaurants are not really Mongolian or even barbecue, it would definitely be a good project to go back over them all, start using a "mongolian_barbecue" tag, and add notes to "mongolian" and "barbecue" in the wiki.

These kinds of projects should be much easier now that misspellings and incorrect delimiters have been corrected.

Caused by osm.org/changeset/131520276

Fixed in osm.org/changeset/131522973. I found the restaurant that should have gotten the tag, it was Wing's 'N More in College Station. I spot checked the others and it looks like the cuisines and other tags were not affected.

Oops that was a mistake. There was one restaurant with a cuisine along the lines of "cusine=burger;happy_hour" so I changed it to "cuisine=burger" and "happy_hours=yes". It appears that I accidentally had many restaurants selected and applied the change to all of them. I still have the data downloaded in JOSM so it will be an easy fix. Thank you for noticing it and letting me know.

Hi ChaireMobiliteKaligrafy, I used the offset for the change and for all my other changes in the area. I'm the same one who added the buildings here last month, I just changed my display name recently.

Okay I fixed it!
