I‘ve never developed a liking for coffee but DW says Costa (not helpful as you don’t get that in the US) but otherwise it’s always been Starbucks for her when we’re over on your side of the Pond. Sadly neither makes an acceptable cup of tea... 

Love Caribou but the only one around closed up. While everyone else has been buying toilet paper I’ve been stocking up on Caribo coffe, always make sure I have at least 3 boxes for the KeurigTruthfully, neither is my first choice. I like Peet's or Caribou for chains, but my favorites are the small local roasters in my area. I love a strong, dark roast and to me a lot of restaurant coffee tastes more like someone waved a brown crayon through some water. So I don't mind the "burnt" taste in Starbucks, but if I'm just trying to get a coffee fix I'll go to the place with the shorter line, which at WDW is Joffrey's. Joffrey's tastes a bit thin and old to me, but it's coffee, so I cope.
But oh, that first cup when I get back home and get back to the local coffee place! That is heaven.
