Their regular menu is great, but their specials are just that - special. I would say that 90% of the time I eat one I say something along the lines of "this is one of the best things I have ever eaten", and I truly mean it.
The only thing holding them back from being 5 stars for me is that I don't enjoy the coffee selection they have out regularly (an important thing for me) and I wish they were open later.
I keep wanting to eat brunch at different places around Madison, but I am continually drawn back to Crema. Also, it gets really busy, so plan ahead!
