We went for an early (6 PM) pre-theatre dinner last night at Bistro D'Oc on 10th Street, NW. My spouse and I shared a very good walnut, apple and blue cheese salad. For her entree, she chose what was essentially a veal stew (though they called it something else). She pronounced it excellent, although she thought the pieces of veal could (and should) have been trimmed of fat more carefully. I had the hanger steak and frites. The hanger steak had good flavor but was chewier than I expected. Perhaps this has to do with the cut of this particular piece of meat, but -- since the beef in question was allegedly Waygu (sp?)/Kobe -- I was nonetheless surprised. The frites were outstanding. My daughter had tuna, served on top of a nice green salad. She requested that the tuna be cooked medium, instead of rare (as it appears on the menu). It came out rare and had to be sent back. After a bit more cooking it was fine. We enjoyed a bottle of one of the less expensive Laguendoc (sp?) reds on the very reasonable wine list.
All in all, we will gladly go back. The prices are gentle and the food and service good. Next time I think I'll try seafood or one of the daily specials.
I note that, although there were a few tables occupied while we were there, when we left for the theatre at 7:45 we were the last remaining customers. I understand that they do a good lunch business, but their current location -- in the middle of a rather seedy block (which has been torn up for ages) next door to the "House Where Lincoln Died" -- may work against it in the evening.
Finally, in response to a question posed yesterday, Bistro D'Oc is very informal. Most of the people we saw while we were there were in business attire, but that's because they came straight from work. Khaki or jeans would not be out of place.
