Country Goodness sells health foods, & typical fudge, & rock lettered throughout with your favourite seaside resort &/or /football team. I found them very helpful & enthusiastic.
They are on the quay between Brixham Tackle & Bait & a Fish & Chips shop, 100 metres NNE of the Golden Hind Ship/Museum.
The Brixham Tourist Information Centre is in the kiosk on the quay at the prow of the Golden Hind, in the South West corner of the inner harbour.
A search on Google Maps for Brixham, then Golden Hind, should find all of the above, all very close to the bus station.
