I stopped in to The Oinkster for lunch last week and had one of the best burgers I've had since moving to LA - nice hand-formed patty, pleasantly charred on the outside and perfectly juicy medium rare on the inside. I liked the burger so much in fact, that I returned on Sunday with a friend. Based on my recommendation, she ordered the burger as well. Sad to say, it was a major letdown. The patty was still perfectly cooked but it was significantly thinner and the meat tasted like it was of lower grade. In addition, it had a "too perfect" machine formed appearance.
The fries were excellent on both visits.
Also, the staff was very attentive on Sunday when it appeared that our order got screwed up. An additional burger was cooked and offered to our table free of charge.
I sent this in to the Oinkster's website as well. Anyone know if they actually pay attention to diner comments?
