In the United States, bratwurst are usually eaten with bread (a hot dog bun or a hardroll, for example) and topped with mustard and/or many of the other condiments often eaten with hot dogs, including onions (grilled and/or raw), relish, sauerkraut, etc. The bratwurst is occasionally eaten with a pair of brat links nestled in a buttered hardroll with these same toppings, which is called a 'double brat'.
