Last night my husband and I went to Park Slope Grill because we were in the mood for burgers and the BYOB sucked us in. From the menu it seems like it's trying to be 7th Avenue's answer to Bonnie's.
We ordered cheese fries, buffalo wings, and a couple of burgers. The cheese fries were steak fries that had a microwaved slice of cheese fused to them. The wings were something that you bought at Key Food and put in a toaster oven at 2 AM on a Saturday night. The burgers weren't that bad though. Nothing spectacular, just an average burger.
They are also still trying to get it together with the service. Our waitress however, was very sweet and kept apologizing and told us they had only been open for 11 days. I still thought that was a little strange since they are owned by the same people who run Olive Vine.
I don't think we'll return there except for a very, very, last resort. Bonnie's has nothing to worry about.
