I can't really comment on the lunch or dinner options at Bill Johnson's, because they don't have much, if anything, for a vegetarian like me. They do have some decent breakfast though.
The Big Apple is right down the road from us, so we find ourselves here for our first-o-the day meal once in awhile. They make a good veggie omelet and the Spanish omelet is pretty good too.
The good: Tasty omelets, hashbrowns (we order em "crispy") & toast. Delicious salsa.
The bad: The water from their "big filter" tastes terrible (to us). If you're getting water, make sure to ask that they get it from the soda fountain filter. They have no variety of tea, just some black lipton. Wish they had some green tea and some other types.
Pro tip: you can buy a bottle/jar of salsa to go for only $2.50. It's good stuff.
