I had a Kobe burger at Brasserie 360 recently. The burger was average. I have not sampled the Kobe burger at Old Homestead, but have sampled the two versions of the db bistro moderne burger many times (non-Kobe). I believe the db burger is markedly better.
That being said, the Brasserie 360 burger is very reasonably priced at $14.50 (for either the cheese-less version or the cheeseburger). It comes with tomato slice, raw onion rings, etc. on the side (I added the onion rings). The cheese choice was cheddar or swiss (I chose the former). The bun had slightly-sweet-brioche-like connotations, and was quite soft (in a good sense) and well-executed. The meat patty consisted less of "ground up"-type meat than most patties I've sampled. However, the Kobe (Western US, to be clear) aspects of the beef were not highlighted in the patty, and that is why I did not rate the overall burger particularly favorably. It is appropriate that the diner has a choice of cooking level for the patty (I chose rare). Took this in with a glass of Jean Luc Columbo 2002 red.
I'm sure this has been reported already, but the former chef at Atlas is consulting chef to the non-sushi part of Brasserie 360.
For viewers interested in aged digestifs, this venue has 1985 F Darrozze armagnac at $45/glass.
