Haven is one of my favourite spots.
Tiny. Literally a hole in the wall. Only seating during the summer and strictly outside, unless you count the tiny stool you can sit on if you become friends with the barista (which I am, duh)
Really delicious, unique espresso based drinks and a really great loose tea selection too. My favourite is the Nutella latte of course
Fun, talkative baristas. Owner is super fun and friendly.
