Best vegetarian restaurant I have ever been too. I have had three different meals there now, and my favourite so far has been the Zen Latino.
The food is divine, and I love the service of the man who regularly serves me. He is so personable and into his food!

Approximate cost: $22

Their coffee is sheer decadence, I don't go anywhere else in Carlton for my coffee.

Being a regular, I have experienced both sides of their service, and whilst never rude or unfriendly they can leave you standing at the register for a bit long.
I also am not too keen on the mass tables the place has, and how they cram strangers on the same table.
However it is a compromise I am willing to make for the best coffee in Melbourne, and some of the nicest breakfast options!

Approximate cost: $12-$18

I love Cobb Lane! Definitely my breakfast spot that I take all my friends too.
The service people are really friendly and accomodating. Coffee is always perfect and the meals and pastries are delicious. Would have give an overall five stars, but more often than not you have to wait for a table because it is quite a small establishment. I guess that just demonstrates how awesome the food is!

Approximate cost: $15
