There are far better options in Little India than Siddhartha. I'm always surprised when I see several people occupying the tables within, however it usually serves as a sad introduction to those not familiar with Indian food in the least.
Usually, once people try the other options available within Little India and elsewhere in the city, rarely do they ever return.
The food looks just fine, when squinting 5 feet away, but then as you approach you note that many dishes are ridden with food colouring, and floating in water. Once you try your first bite, you realize that everything is sugary, even the chicken.
I would rather take my friends to Haandi or Mahar down the street. They won't hate you for it afterwards.
