When I visit the Del mar area, Bully's is always one of my stops!! The prime Rib is very good and the other serving are certainly above average. Friendly staff and a nice local crowd. Within walking distance of many bars and clubs.
Bully's is one of the very few places in North County San Diego where you can actually eat a decent meal after 9 PM. The prime rib is the dish of choice, and I'd say that Lawry's (up in L.A.) is the only prime rib that trumps it. Against all other competitors, Bully's stacks up nicely. I'd recommend a gin & tonic at the bar while you are waiting to be seated. The decor is pretty sweet, too. Low key, but still nice.
