Sardine is a hard place to find if you're not a local. It is hidden by lake Monona terrace and traffic can be a pain. I've only been here for brunch, but the food was delicious. Sardine is definitely a higher end brunch spot with many options that you will crave.
I had the omelet with goat cheese, bacon lardon, cherry tomatoes, and spinach which was delicious and prepared in a timely manner. This came with a side of fruit. The plates here are a bit expensive, but the food is delicious.
My only regret is not trying their homemade pastries which looked incredible...until next time...
