Coffee= Lavazza or Hasbeans Monsoon Malibar,freshly perculated,black strong.
Tea=Much as it pains me to say but Yorkshire tea is the best with Twinnings Earl Grey a close second,black,strong.
Why anyone wants to pollute good tea or coffee with milk or sugar is a mystery to me
PS If you want to sweeten either of the above drinks eat a Kit Kat (four finger one)with it
BTW In a decent coffee shop I don't mind the wait for a decent coffee
