Sushi, Indian or Pho near 15th and G?
Naan and Beyond isn't bad for what it is. over by L and 19 there's Asia Bistro and Nooshi.
the by-the-pound sushi buffet in the Press Club food court (part of the Soho market) can be hit or miss - and they will make to orders, but over-sized pieces that often lean towards the gimmicky. AOI sushi up at 11th between H and NY Ave.
<edit> forgot about Cafe Asia at 17 and I - but it's so freakin' loud.
