Literally stumbled upon a great brunch in Georgetown this weekend, careening down a flight of steps (crappy 3 year old sandals) and landing up at Leopold's Kafe in Cady's Alley (can't remember the exact entrance, but general vicinity was M street, west of Wisconsin on the south side of the street). Figured the quiet terrace sandwiched between the uber-expensive Scandivanian design shops was a good place to figure out whether the sandals were salvagable or not; ended up sticking around for a bite to eat.
Coffee was fantastic. Came on a small metal service with a tiny glass of water for a post-coffee 2 or 3 sip gargle. Very euro-trashy, but delightfully so.
Roast chicken was surprisingly top-notch (a risky order at an unknown restaurant). Skin was crispy, inside was juicy, came on a bed of lettuce with a salty, mustard sauce.
Friend ordered the veal schnitzel, which looked great, but he's got a phobia with sharing food so didn't get to stick my fork in.
Highlight was definitely the desserts. The lemon tart (torte?) was just the right tartness, and had a meringue on top that seemed to be mixed with marshmallow, as it mantained a gooey consistency. Friend had the Sacher-torte (? -- i.e. dense semi-sweet chocolate cake, I think) which I couldn't really taste (that damn phobia acting up again) but friend said was good. He's of Austrian descent, with a grandma who occassionally whipped up these Sacher-tortes back in the old country, so I can only assume his opinion is somewhat credible.
I've heard Leopold's has been criticized heavily on the service. I thought the service was perfectly adequate. Definitely not the doting you get at some of the more expensive DC institutions, but for a laid-back terrace, there was nothing to really fault (they've also got a sizable interior with lots of little tables and some weird, funky couches, no doubt purchased from the uber-expensive Scandinavian design shops that surrounded us).
At last a better alternative to Clyde's and Peacock..
