You don't have to visit Alnwick Garden to eat at this extraordinary restaurant set among the treetops. The location may sound gimmicky, but the effect is quite magical, especially when the place is lit up at night. The modern British fare is excellent—Northumbrian lamb with smoked cheddar and potato gratin, perhaps, or North Sea hake with boullabaisse sauce and saffron cream. From July to September, the kitchen only serves prix-fixe menus at night; the rest of the year there's an à la carte selection. You can grab a light lunch or tea and cake at the Potting Shed bar, which is also open for predinner drinks.
