Mandu is a nice, but low-key Korean restaurant, and it’s a good spot for a date, group hang, or solo catch-up with the friend you only see once a year since his move to Petworth. It’s inexpensive enough for a casual weeknight, and even cheaper if you get there during happy hour from 5-7pm. Get a few aloe sojutinis (soju mixed with a fruit juice of your choice) and an order of fried mandu, and you’ve got yourself dinner for under $20 - which is a great deal if your rent in Shaw just went up 20 percent. They also have a location in Mount Vernon Triangle.
