Pluses of Bluephies -- good place to get a table for a lot of people, very friendly to small kids. Very broad menu, so very unlikely anyone wouldn't find something to eat here.
Minuses. Since there are tons of kids here, it would probably be an annoying place for people who find kids annoying. More importantly: everything I've ever eaten here tastes about 75% as good as I expected it to from the description on the menu. Nothing's really wrong with the food here; it's just -- not that great.
