Recently I switched from Google Fi to AT&T for similar reasons. After I transferred my number out of Google Fi, there was a questionnaire from Google asking why I switched, and interestingly, among all the selections (coverage, price, etc.), there was not an option mentioning customer service.
For food scene, yes there are a lot fancy restaurants with long queues, but there are also many authentic Chinese / Korean restaurants here. It's just these restaurants are not well known and mostly serve local people, and usually you cannot find them easily on Yelp due to low ratings / reviews.
