Extra Info


The Walnut Tree Restaurant serves food, 6 days a week from 7:30am to 2:30pm, and both breakfast and lunch menus centre on the very best produce from around the county, picking the best of what is in season.

They can cater for a host of dietary needs.   Gluten and dairy free options are available and the menu is well beyond the standard you expect from a health club or spa.

The Walnut Tree Restaurant is comfortable with plenty of seating to drink and dine, catch up with friends, read the daily newspapers, or perhaps relax after a tough workout – all in an adults-only surrounding.
