Bismi are now doing an all-you-can-eat lunch buffet from Mon-Wed with around 25 choices including dosai, roti, dhal and several vegetarian (8+) and non-veg curries.
For $11.90 it is great value but it certainly won't be good for my waistline. I'm going back tomorrow!
Bismi has without a doubt the best masala dosai in Melbourne - crisp, paper thin and very very tasty. I've been enjoying them for around 4 years now and I think they might even be getting better.
Their roti and thali dishes are great too. I can't comment on the biryani or meat dishes - never made it past my staples.
I think they might have recently turned down the music (at least when I was there) and it's possible they have even have given it a clean!
I would probably still frequent this place even if it was the grottiest in Melbourne - the food is that good.
