It is a fantastic location but the drinks prices are so be aware.
Lots of City places open up for breakfast so I'm sure you can find somewhere good there as long as you don't mind sharjng the place with suits. Hawksmoor Guildhall does fabulous breakfasts and great cocktails/Bloody Mary's too.
That's it really...girls night out coming up and we're looking to round it off with a champagne brunch the next morning. Have had a look online but can only find places doing Sunday brunch and we'll be looking for mid-week.
