Is there a list of Northern Indian dishes?
Someone on the SF board was asking about restaurants serving Northern Indian food and another poster asked ...
(1) Is there a master list of which dishes are characteristically Northern Indian? Or dishes that you particularly are looking for?
(2) Is a restaurant's web site likely to state that it has particular expertise in Northern Indian food? Should such statements be believed?
I don't know a lot about Indian food. Does this seem like a reliable resource.
I don't think you should look at Indian cuisine as simply Northern vs Southern. This will only lead to shallow and sometimes incorrect generalizations.
Don't worry about a restaurant's marketing - what they say about their food. Most places don't want to limit their menu and possibly narrow their appeal.
I suggest starting with the list of regional Indian cuisines on your website, and look them up in Wikipedia. The wikipedia page will have some basic info, but more importantly will reference other specialized websites to give you detailed info.
Definitely start with thinking of Indian cuisine as regional.
