Love the cat! The coffee is tasty, good variety of pastries, and the baristas are friendly.
In the summer I recommend the iced coffee. You can have plain or flavored iced coffee and the ice is slushy (like Sonic or Chickfila) so it's a nice surprise if you're used to the cubes at Starbucks or Dunkin.
Definitely sign up for a VIP account if you'll be stopping here often or you're social media savvy. Smelly Cat rewards it's VIPs with special treats (check Facebook or Twitter for postings) and with each purchase you earn other rewards like free coffees. I really love a place that loves it's customers like Smelly Cat does.
