In one word: overrated, just like every other restaurant on this block (maybe with the exception of postino). Zinburger is catered towards hipsters and soccer moms who think casserole is a good meal.
The service is sort of laughable. Our waters were empty so many times I ended up getting up and pouring water from the pitcher close to us.
I had a veggie burger and zucchini fries. The food took a while to come out and the server messed up my order. The veggie burger was not bad. I eat meat and I'd consider getting it again. The bun was just so sad. It was dryer than Arizona in the winter. I ended up eating the burger with no bun because I couldn't swallow the bun-- especially without any water in my cup. The fried zucchini was alright, but it did lack salt. I also tried my friends burgers and they were not seasoned or cooked well which is a huge issue for a burger. Save your money and find somewhere less pretentious.
