The best restaurants in Headington Oxford South East

I have ordered coffee 4 times there over the last 6 months, and everytime it has been undrinkable. The Americano in particular is bitter water with no taste of coffee. I noticed that their espresso brewhead is much shallower than most coffee machines, so they pack much less coffee than in other cafes. I had coffee with other people here and all have the same complaints. The cakes and pastries are fine though, that's why I give it a 2.
