Portland had this before the pandemic, maybe partly due to the size of the restauarant/food service industry here. Some examples include http://www.rinellaproduce.com/products.html and https://www.sheridanfruit.com/. They're wholesalers but have always been open to the public.
Our local restaurants also jumped quickly into selling meal and beverage kits alongside single takeout/delivery meals, and breweries expanded shipping options to serve individual homes. Meat and vegetable farms too, most of which already had the infrastructure through CSAs/farm shares.
