Thanks to those who posted to my request for crab cakes in DC; the only place we tried to get to was the place in Eastern Market, but they are not onen evenings. Spent six days in DC (there were four of us), here are some restaurant reviews for future visitors.
If you are in the military (or are retired or know some one who is), go the the Sunday brunch at the Fort Myer's officer's club. Great bargain ($16 per person) and a wonderful meal. Also had lunch at Old Ebbit Grill (ask for the courtyard, much more open and no smoke). All the food was first rate (oysters,clam chowber, crab cakes, french dip sandwuch and grilled chicken salad), service was excellent. All other lunches were in museum restaurants, the only thing notable was the McDonalds at Air and Space. Food was typical fast food, but the building is HUGE!
Orleans House (Rosslyn) Great bargain! Salad bar was big and all ingredients fresh, prime rib was great and the crab cakes the best we had.
Portofino's (Crystal City) Wonderful meal and wonderful service. Calamari were excellent. Thought the best dish was the veal stuffed tortellini with a gargonzoga sauce - yum. Other dished (fresh tomatoes with mozzarella, lasagna, pesto pasta and pasta with eggplant) were also excellent. And you can order an appetizer portion of any pasta.
Legal Seafood (our choice after we found out the Eastern Market was not open evenings). Everything we tried was fresh and well prepared; a can't miss place. The clam chowder was particularly good as were the simple, but well prepared fish and chips.
Warehouse (Old Town) Another great meal. Best calamari we've had in a long time. Crab soup was different (more tomato and spicer than others) but tasted great. Crab cakes OK. Mahi Mahi with a hot mustard and pecan crust was really good and the veal chop with a tasso and mushroom sauce was excellent.
Bistro Bis (Capitol Hill) GREAT restaurant. Attentive service, good selection of wine by the glass and a really pretty space. Steak tartar was good (prefer to mix my own - this one had the egg, onions and capers already in it, they would probably have left it seperate if I had known to ask). Outstanding endive salad (wife said it may have been the best salad she has had). The lamb shank was marvelous and the onion soup, oysters and onion tart was also really good.
Only disappointment was a quick supper while shopping at Pentagon City mall at L&N Seafood. Have have good chowder there before, this was dishwater.
