My god this place is good! Even though it's a good 25 minute walk from where I work, we make a point of going there once a month to pick up rotis because they're crazy-flavourful. I always get the lamb roti (very rich and savoury) but I've also tried the chicken, chicken vindaloo, and saag paneer rotis and they're all excellent as well.
I would recommend going one step in spicyness less than you would usually order (eg I usually order food medium, here I order mild-medium) so that you can fully taste the wonderful curry filling without being overwhelmed by the heat.
The meals are cheap and large enough for two lunches... people eat here but I'd recommend calling ahead and doing takeout, as the ambiance isn't exactly existent.
