Does anyone know where there is a good all you can eat indian buffet near to West Street?

Simple - there isn't one. Used to be one called "Cha Chas" but it closed and is now under redevelopment.

Oh dear.

Is there anywhere fairly cheap but decent around there to eat in the evenings? I'm out with a couple of friends tonight around that end of West Street and I wanted to grab something quick to eat before drinking.

There are Chinese buffets a-plenty, if you're after a buffet style restaurant.

Nando's is decent value, if you like spicy chicken.

That noodle place in/under West One is quick, fairly cheap and pretty good quality, and I've never been able to finish what they've given me (because of the amount, not the quality).

Food at Iguana's is good but not cheap.

If you want Indian buffet try Eskitinum. Very nice. Downside is that you need to go to Darnall.
