My experience in Chiang Mai was a little over two years ago.
Maybe the system has changed, but I thought that the consulate at which you apply is specified on the invitation letter by authorities in Kunming (based on your request) and that consulate must process your visa.
For example, when I did it in Hanoi many years ago, the Hanoi embassy was not accepting tourist visa applications from non-Vietnamese. And, while they didn't seem thrilled to see me, they nevertheless duly processed my Z visa because I had an invitation letter specifying that I apply at the Hanoi embassy.
Again, my info us out of date, and I know there have been a lot of changes in the past few years.
I don't think success rate is an issue. My understanding is once you get the invitation letter, it's basically 100%.
I've done it previously at Hanoi and Chiangmai. I remember them being a bit on the slow side (any maybe not having an expedited service for extra fee available?). Maybe a two or three business days, something like that.
Alas, no robot bartender. And, actually, because the whole chain and concept is very home delivery-centric, almost all of the fresh produce is packed on plastic trays and shrink-wrapped — or otherwise packaged in wasteful ways. This is necessary for being able to provide unit pricing, automate inventory control so that delivery customers don't end up ordering stuff the store does not have, and speeding the preparation of deliver orders. So, pretty alarming from an environmental standpoint when one considers this is the way the whole supermarket industry seems to be leaning in China.
I've been taking boxing classes with Kasey, who is an excellent teacher. The studio is no-frills, but they have a wide range of yoga, self defense and other classes. And some of the teachers even donate the class fees to charity. Glad to have Spring City Yoga Collective as part of the community in Kunming.
Stopped in today while out on a motorbike ride. Nice place to chill out away from the hustle and bustle of town. Can swim in the reservoir nearby (although technically prohibited, nobody seems to care). Great pizza. Good coffee. Reasonable price. As previous reviewer mentioned, if you're going there particularly, it might be worth calling and double checking they're open and arranging for food. Owners speak English.
A welcome addition to the Western choices in Kunming! Good bread, world-class pastry art, a small but solid food menu. Would suggest a little more flavor in the tomato pasta, and eggs benedict would be even better if on an English muffin instead of bread.
A nice day out. I missed the second exhibition. The third exhibition, currently ongoing, is contemporary photos of the Kunming-Haiphong railway, mostly the Chinese side. I thought it was quite good. It's not a huge space, but the 1903 commercial complex has some decent dining options (including the museum cafe itself which has some expensive but very good single origin coffees).
