Bonnie's Grill, steer clear of the veggie burger!
Just had one of the most disgusting and objectionable meals of my Park Slope life at Bonnie's Grill. Hubby and I ordered veggie burgers with fries. No complaints about the fries, which were freshly fried, crisp, and delicious with the tabletop mayo. The burgers, however, were another story entirely. Black, burned, and smelling of my grandparent's ashtray. It was foul. We considered sending them back, but were hungry and the beer had kicked in, so we decided to soldier through, hoping the char wouldn't be so bad. As it turns out, that was the wrong choice... about 1/3 of the way through, I tried to scrape the black crust off my burger, which was not terribly successful. Of course, our server took no notice of my pile of black crud or my husband's 1/2 eaten burger.
This was the second time we've received burned burgers at Bonnie's. Let's just say, that was out last visit to Bonnie's. Now, if you'll excuse me, I have to find something to get the taste of charcoal out of my mouth.
My "beef" (har har) with Bonnies was always that the burgers had too much char on them. My friend tipped me off to ordering them without the spice rub, and that made all of the difference. I'm not sure if they do the same thing with the veggie burgers, but you could check on it.
