It's not called a French dip but the Hot Beef at Tat's Deli with a side of au jus is the best French dip I've ever eaten. House roasted beef, provolone, peppers, horseradish on the French roll. The au jus is really good.
yes do be forewarned of that since most of us are used to dipping our own, but at the risk of sounding snarky (i merely intend to be informative) the kitchen doing the dipping was the original meaning of the french dip where it was invented in la.
Thanks for the suggestions! I did try the prime rib dip at Bing's today and it was very good. A bit pricey for an everyday lunch ($13.95 for sandwich and potato salad), but good for the the occasional craving.
