I have eaten here several times as I'm vegan and I have family in the town, some of whom are also vegetarian. I have always had good experiences with the Waterside Cafe's salads and soups, and the chilli is really good. It is true that there are fewer vegan choices than lacto-ovo vegetarian choices, but that's the same with most vegetarian eateries.
I want to just point out that this cafe is too small to have table service - you order and pay at the counter before the meal is served, like a cafeteria.
Cons: Small, No table service
