The signature honey butter latte ($5.50) is equally delectable. Ask for less sweet - otherwise the sweetness tends to be a bit too overpowering. The espresso at Mad Roaster is noticeably well balanced with light hints of acidity and bitterness that can still be appreciated despite the honey butter flavoring. The honey butter flavour itself is delicious - very toasty and buttery. Reminds me of butter pecan. 5/5.
