Every time I google "best burgers in New Jersey," the same 10 places show up, many of which I've visited, and many of which aren't very notable (White Manna, I'm looking at you). It's getting a bit tiring. Fatigue be damned, I put myself through the same exercise a few days ago, and finally conceded that I should probably give the Trap Rock Brewery a shot.
Trap Rock is part of the Harvest Restaurants group, which includes a bunch of places that seem to be very similar to Trap Rock, and the Roots Steakhouses (auto-play warning), one of which is set to open in Ridgewood, NJ, in, what, a year or so? (Did they really think they'd get it off the ground by October? In Ridgewood, a town known for pain-in-the-ass inspections and bureaucracy?) From what I can tell from a few visits, their restaurants are well-run, their staff well-trained, and they do a competent job. My first visit to Trap Rock supported that theory.
You can review the menu online, but I was there for the burger. Trap Rock offers two burgers, one of which is made from grass fed beef, and seems to be their signature. Their other burger is "just a cheeseburger" I was told. Not that there's anything wrong with that.
I went with the 'TR Local Grass Fed Burger' (the burger is not grass fed, but the steer presumably was). This burger is served with Red Dragon Cheddar (a cheese of Welsh origin, with ale and mustard seed), rosemary aioli, and caramelized onions. A lot going on there, and not much in the way of bright, crisp flavors and textures that I usually enjoy on a burger (raw onion, ketchup, good, ripe tomatoes). I ordered it as it's designed, and was pleased to see some raw onion and ketchup served along side. I put a bit of each on the burger, to hedge my bet.
