I dined in Mooli (from the Guardian link posted by ajax). Cor.

Basically an Indianised burrito for a fiver, the chickpea version I enjoyed was really lovely with big, bold clear flavours. Add a mango lassi for £2 and poppadum crisps with dip for a quid and I was a very happy boy. Got chatting to the co-owner and commented they had a great concept to rollout. He just grinned.

It's next door to the utter divine Koya which serves amazingly good feet-made udon noodles with in house dashi stock. A bowl is £8 or so - real value for the quality - but word is out and you can queue for 30mins to get a table.
