Places for Hen Night Drinking / Pub Crawls in Edinburgh

I am doing a bit of research into Hen Nights in Edinburgh. 

Does anyone have any suggestions for hen night areas to go drinking. 

I have George Street (click to see what i have gathered http://www.informedwomen.co.uk/travel-events/edinburgh-hen-parties/sophisticated-hen-nights-edinburgh-upmarket-hen-nights-edinburgh) as a more upmarket area and

Grassmarket click here to see what i have so far http://www.informedwomen.co.uk/travel-events/edinburgh-hen-parties/hen-nights-edinburgh-pubs-and-clubs-hen-nights-edinburgh-grassma) as a more fun and flirty place to go are there any other areas.

But are there any other great hen night pub crawls in Edinburgh? - thanks
