Stopped by the Costco in Los Feliz yesterday and to my surprise, they had prime tomahawk rib eye steaks and bone-in t-bone steaks. Each steak was cut to about 2.5-3" thick. The tomahawk was $14.99/lb and was individually packed at ~$40/steak. The T-bones were $11.99/lb and packaged in two’s. Both these prices are pretty fantastic.
I’m not sure what availability is like in other Costco’s but if you’re near the Los Feliz location, go check it out!
