Either:
Take the B3018 Out of Bracknell (up past the Stag and Hounds) to Twyford. Turn (nasty bend to see around) right into Howe Lane. Pass the Bottle Lane junction on the right. Beechers is on the right just past the bend.

Or:
Take the A3095 Out of Bracknell to Maidenhead. Bear right past the Three Legged cross still toward Maidenhead. Take a left at Bottle lane. At the end of Bottle Lane turn right onto Howe lane. Beechers is on the right just past the bend.

Small pre/Post meal bar (Have a quick one and inspect the place before you book). Restaurant with good food. Serving lunchtimes and evenings. Interesting stuff to choose from on the blackboard as well as the menu.
