I adore their breakfast items, except for the cactus. Cactus did nothing for me.
They have delicious coffee, are great with kids and they are always busy. You can expect to wait 20 minutes for a table on the weekends.
They are pretty good about allergies. Gluten-free is not a problem for them, 99% of the time. My wife with celiac's disease prefers them for that reason. But just once, she had a reaction from eating there. Just once, which is a better track record than many restaurants we've tried.
