We just got back from Brent's Deli in Northridge. I had the roast beef au jus, and my spouse had the pastrami au jus. It was close to $30 for the two sandwiches (!)
The pastrami was OK, but not anywhere close to the massive portion I had expected from reading reviews on here. The roast beef was dry. The rolls were meh. And the au jus was just...not very good. The fries were a little sweet.
Never again -total rip-off. However the fruit salad, which I got instead of the cole slaw, was delicious, maybe because it was the only thing moist and juicy in my meal.
