Have you tried finger foods yet? Around that age, it's pretty common to refuse everything but finger foods. You might give that a try. And be sure to keep offering bottles and sippy cups. Letting her starve for a couple of days isn't a good idea. Babies and toddlers have an innate ability to regulate their appetites, and you'll find that it varies quite a bit. Teething, milestones, illness, and just about anything can put them off food temporarily.
Do your best to go with the flow and not let her see your frustration! If she doesn't want to eat, don't force it. She'll come back around!
