Tea can be enjoyed with or without milk. Most of the time I would drink it without milk, sugar, cream or any other condiments as I prefer teas which are nuanced and naturally aromatic - (Mostly Darjeelings, occasionally Oolong, etc). It also helps avoid calories unnecessarily. Traditional flavored tea like Earl Grey, Lapsang Souchong also can be enjoyed without milk or sugar.
However the following also hit the mark occasionally
1. Strong tea (Assam, etc) with cream, sugar, Ginger, Green Cardamom, Saffron. If cream is not handy milk is also OK, but best variety of this should be like a milkshake. Also tastes good with Earl Grey.
2. A strong tea with a dash of lemon, a hint of sugar and rock salt. This is a savory tea
