What a delightful place!
I have eaten at Coca Cafe twice, and both times have greatly enjoyed my experience.
Let's start with the place--a fun, hip locale right in the heart of Lawrenceville. There are colorful tables with bright splashes of color all around. There is a room with more tables in the back, as well as a few tables outside on their patio.
There is a nice selection of food. Now I have only been there for breakfast, but I glanced at their lunch menu. Both breakfast and lunch have tasty selections who are also friendly to vegetarian/vegan needs. Both times I have had their challah french toast (anything with challah...oops almost said HOLLA! is delicious) which is served with fresh berries. I felt like the prices were reasonable too.
Come check out this place! Definitely will be crowded on weekends so I recommend coming early, or on a week day if possible.
