I settled in and ordered:
Chapatti (though I got both chapatti and roti in the end)
Papad and beer
Rice (I asked for basmati but was told it was only included in biryani)
The beer and papad came, and they went down well. I had to wait quite a while for the samosas – the guys on the other table had ordered a fair bit, and I got a pang of food envy as each delicious looking dish flew past my head – so I ordered another beer (came with more papad, luckily). When the samosas came, it made up for the wait. Both were steaming hot and the soft potato enclosed in a thick crispy layer went down brilliantly with a couple of small bowls of tomato sauce (one was standard ketchup but the other, tangier variety made me think I’d hit the jackpot (see: Maggi). I didn't ask, though – was too wrapped up in the food).
It's a bit of a squeeze in the restaurant, but the guys running it are friendly and the service, value, atmosphere, and food quality right up there with the best in the area. And I can understand why it would attract those looking for quality, authentic Indian cuisine. A guaranteed to please option for anyone in the area, it's going straight on the JIMC recommended list. Between Kinshicho and Ueno/Okachimachi, you can just about fulfill all your curry needs. If you see someone eyeing up your food enviously, don't worry. It'll probably just be me waiting for my samosas.
