Why settle for chicken tenders and fries from a concession stand when you can snag a fabulous burger at Drinx (601 F St., NW; 202-661-5040), a new sit-down bar/restaurant at the MCI Center? Made with Angus sirloin, the flavorful, perfectly cooked burger leaves a lovely ring of meaty residue on the onion-crusted bun. What takes it over the top is the slightly sweet house tomato-brioche chutney and a scattering of thin, crunchy buttermilk-battered fried onions. At $10.50, including shoestring fries, it's just $1.50 more than those chicken tenders and almost as fast–we were told it would take ten minutes, but it showed up in five.Washingtonian staffers contributing to this section were Cristina Abello, Susan Baer, Susan Davidson, Ken DeCell, Rebecca Dreilinger, Kim Isaac Eisler, Mary Clare Fleury, Kimberly Forrest, Brooke Lea Foster, Garrett M.
