Not awful, but certainly not that good. After 4-5 visits, I only go there in a pinch, or when I'm asked to meet others there. I wish it were better, because it's so close.
The good: Decent craft beer selection, terrific service, great location, patio dining.
The bad: Underportioned for the price (sides/fries are much bigger at Delux), quality (burgers aren't as good or as imaginative as at The Grind).
I'm happy to drop $15 for a big, awesome burger and a big order of really well done fries. But Zinburger doesn't deliver that.
Went again last night for a get-together and tried the Asian Chicken Salad -- small portion for $10 or $11 and totally unmemorable. Had a nice Four Peaks Ale and Sierra Nevada, though.
