I almost always get the Brisket sandwich but for some reason I tried the burger the other day. And I have to say it was excellent. As we discuss the best burgers in Westchester, which is a perennial discussion, Q needs to be factored in. And, though I'll probably take some arrows for this one, I would go there before I go back to Pipers Kilt.
A bit about their burger. First, they use very good beef - and a perfect amount. Not obscenely large, but not skimpy at all. Probably around 10 ounces, I'm guessing. Second, they actually cook their "medium" burger medium. Nice and rosy. Third, the bun is excellent. I'm guessing the Q connection to the Kneaded Bread bakery helps here, but they serve the burger on a great brioche bun.
I got my burger with blue cheese and bacon. The bacon is nice, flat smokey bacon.
Comes with lettuce, tomato and onion on the side if someone so chooses.
Anyhow, a very good burger. I was pleasantly surprised.
BSF is just around the corner so it's worth a comparison. These are different burgers, really. Q's is more of a higher end restauranty burger. (realizing that sort of makes no sense). BSF is definitely less expensive (Q burger is ~$10). Both use good beef. Q is a fatter burger, and in my experience, more juicy. BSF burger has great flavor. If I go to BSF nowadays it will probably be because it's cheaper, but given a choice between the two, I'd probably prefer Q for the reasons above.
One caveat is that I've only had the Q burger once. So I don't know about their consistency...
