Flavor & Zest has published a review of the White Cap Grille.
For a restaurant in Maine, it has the obligatory seafood options (baked Haddock and pan-roasted Salmon) as well as steak dishes, a Chicken confit entrée and a pasta dish. It doesn’t push the bounds of ingredients or try any complex recipes, but holds its own to the various pubs and American-style restaurants in Portland. It has a nice ambiance and versatility, with reasonable prices (lunch for a three with a round of drinks came to around $55) as well as a cocktail menu and bar for a comfortable stop on a night out on the town, although perhaps not the destination.
