This place is always busy and if you eat there you'll see why. It does look like a greasy spoon gone wrong and isn't the cleanest looking place you'll ever see but the food is superb. It's definitely one to go to if you want something a bit different. It's also dirt cheap.
The menu is quite basic, with lamb and chicken curry on and off the bone spicy or mild. They do a good mince curry with boiled egg, and also they're the only place I've been to that do a curry breakfast (sheek kebab in puri, halwa, dal, spinach omelette and masala tea). Sheek kebabs are also really good, and they do the most amazing pilau rice I've ever had, I'd recommend going there just for that. Boal fish curry is also very good.
The breads aren't great but the rice is so nice that they don't really get a look in, also the menu is a bit offputting if you're not used to it, but go in with an open mind and you'll probably love it. As mentioned it does look like a bit of a s**thole.
It's a good place to go on a sunday afternoon as it's not really somewhere to sit down at in the evening but highly recommended.
