Both of these restaurants are very nearby to each other. Personally i prefer the Malaysia Kopitam. The menu is more extensive. You can get roti canai, satay, mee kari, nasi lemak, nasi ayam, asam laksa, and other Malaysian favourites.
At New Dynasty the menu is limited and the taste is quite bland. Oh well, maybe it's just me... Go check them both out if you happen to be in Washington DC & looking for halal food :)
