The best coffee I've ever had was at a casino in Las Vegas, oddly enough. I tried my best to get them to sell me a pound, but they wouldn't do it.
I normally drink Yuban regular or Yuban Pacific Roast. I also like Don Francisco's or Cafe Bustelo's espresso.
I enjoy hot tea when it gets cooler, found a great bulk loose tea website:
