I couldn't find a topic on this place. If it exists, my apologies.
We went to Cusbah late last week, and were impressed. The food was very good, extremely flavorful (they were not afraid to use heat), and extremely affordable. My goat vindaloo was $11, while my wife's chicken tikka makhni was $9, and it was more than enough food for us. They had some decent drink specials as well (and some appalling sounding mixed drinks, which involved Goldschlager and Jagermeister mixed together).
I wouldn't travel to go here, but it's definitely the best Indian food I've had on the Hill (which is, admittedly, a low bar).
