The Spa Restaurant was established in West Stewartstown in 1927, as a small diner. It was the meeting place for all area woodsmen.

In 1956 a formal dining room was added to keep pace with growing business. After several renovations and additions to the restaurant, in 1994 current owners Francis & Stephanie Grondin added a pub downstairs (The Outback Pub).

In 2022, The Spa opened its food truck, offering take-out as well as outdoor dining under their large pavilion.
