I always pop in to Fahrenheit in the morning to grab either an apple crumble or the banana choco chip muffin - both super delicious. As far as muffins go...they knock it out of the park. They also have really great scones and if you pop in around lunch time, their sandwiches are really high quality and include unique ingredients. And that's just the food! Of course they have amazing coffee too. Love the Americanos.
If you want to see the best latte art in the city, this is the place to go. Sameer is the master. Not to mention the friendliest guy ever!
