Chose Zinburger to enjoy lunch with a friend on the patio & take in the cooler temps. Man were we disappointed!! Let me start by saying the place wasn't even a little bit busy. 3 tables including ours in the patio. Waited 10+ minutes before I went & tract down a waitress. Decided better make the most of the visit we ordered drinks food all at once. We ordered sweet potato fries. When asked if we would like those to come out first we replied yes. Drinks came relatively quickly &&& then the wait. Finally all the food came at once. ?? Whatever we were starving. My burger was missing the bacon & had onions of which I request otherwise. The boy that dropped off the food (still hadn't seen the waitress since drinks were dropped off) he left so quickly I caught him to ask for mustard & ranch. No one came back until the original girl I flagged down came to check I mentioned the onions and the no bacon which I could have lived without but the onions were a deal breaker. She offered to have it remade I was hesitant because I was so hungry but she assured me it would be quick. My friend was almost done with her bun less double double that she requested with the trimmings and condiments that came with nothing. She didn't mention it to the waitress because when she finally came back what was the point she was almost done. The burger came back ... 10 min or so later by the manager who Said so sorry. I again asked for mustard that had never come. I dipped I to my BBQ sauce and found a hard thing like a twig... Happened to be a shaving off the toothpick that holds the buns together is what the waitress explained. After I removed my burnt bun & pulled the twig out of my BBQ I continues to eat my dry burger when my mustard arrived half way through.... In the end the waitress said we comp'd your burger just because we thought we'd be nice! Really...really??? First & last visit!
