The aesthetics are comfortable and inviting, service is friendly and efficient, and cooking seafood has been raised to an art form.
During the summer (tourist) season, there's a healthy mix of local residents and out-of-towners, but avoid the restaurant between 5 pm and 7 pm...it gets packed and there may be a long wait for a table.
Favorite Dish: The stuffed sole, cooked The Mull way, is the best stuffed sole in the world. It is tender and juicy with lots of natural flavour, and the crab stuffing is makes your mouth water. Although pricey (around $12 Canadian), It's well worth it.
Another great dish is the Mussels and Ceasar Salad special that is usually on throughout the week. For about $8 Canadian, you get a heaping plate of steamed mussels and a huge bowl of one of the best Ceasar Salads in North America (real bacon and homemade croutons). They usually sell out of mussels by dinner time, so its best to fill up at lunch.
Although not a physical danger, being a dumb, pretentious tourist can be harmful to your ego when in Mabou. This community of hard-working people take great offense to large RV's moving at 30 km/h on their single-lane roads, to people snapping photographs of every nook and cranny (people even take photos of the locals, as if they were an exotic tribe), and to outrageously stupid questions (I once had a woman stop me and ask "What sort of beer do you people drink here?").
Also, don't pick an argument with any locals, because you won't find a sympathetic ear amongst any of the other locals if you are a stranger, regardless of how in the right you were.
