I am posting the link from the Globe and Mail review because it was indicative of our experience at this restaurant. Nice room, friendly enough staff but the food for price was substandard and the service while attentive was amateur. If you're in the market for five star Portuguese food you would be better off trying Chiado on College Street or Adega on Elm Street.
Flor de Sal is not worth the price of admission.
