The Bichon Frise diet will need to include animal proteins, carbs, vitamins, minerals, and omega fatty acids--nutrients every dog needs to maintain its health in the long term. This means the best Bichon Frise dog food is premium dry kibble, as it has balanced portions of the above-listed ingredients. One premium brand even has a line of dry food specifically formulated for this breed: Royal Canin Bichon Frise Food is tailored to adult Bichons, and has nutrients that keep these dogs at their healthiest.
Specifically how much should a Bichon Frise eat? Adult Bichon food portions are about 1½ cups of dry food per day, divided into two meals. Portions of food for Bichon Frise puppy dogs are a bit smaller: depending on age, about a cup per day, divided into three meals (not two) until five months old.
For more info on feeding these dogs from puppyhood through maturity, here's a Bichon Frise feeding guide:

Try if possible to stick to the above-listed portions. If constantly overfed (and under-exercised), these dogs will become overweight--and a fat Bichon Frise will have numerous health problems and a shortened lifespan. You can help control your Bichon's weight by having consistent feeding and exercise schedules, by not feeding the dog table scraps, and by not leaving food in the dog's bowl all the time.
If you're worried your Bichon Frise is overweight, try this simple test: run a hand along the dog's side, and if you can't feel any ribs, it's diet time--which means less food and more exercise!
