Gorgeous setting for starters. Last year (like this year) I escaped the Burgh at Festival time but had missed going to the champagne bar so this year, I was determined not to miss out and had my table booked a month in advance. \n\nThe Pommery Cafe Bar, hosted in conjunction with the Signet Library is a month long (Festival) pop-up bar offering champagne. This year, the menu was extended beyond afternoon teas to seafood platters and lobster and wedges. The Signet Library as Jenny L. mentioned, offered various vouchers for money off certain deals and these were valid throughout the month. For a budget visit, there were also offers on such as Twitter Tuesdays (15% off for tweeting pics/tweets about the Pommery) and Wedges Wednesday (Wedges and Glass of Champagne for \u00a310).\n\nLobster and wedges were \u00a320 (normally \u00a330 without the voucher) and they were fab. The lobster, although not the Boston portions I had reported on recently, were still decent portions and tasted fresh and delicious. The wedges are a small portion (still tasty with proper garlicky alioli) so don't come ready to eat your arm off. \nWe had a seafood platter as a starter and it was decent enough to feed three of us with drink munchies. Prawns, smoked salmon, beetroot salmon, trout, mackerel pate, bread and salad were all lovely and certainly were a good sign of things to come (sadly, I didn't take a picture). \n\nChampagne is available by the glass, bottle or magnum. I think the magnum is around \u00a3110, a bottle is average \u00a352 and a glass around \u00a311. We opted for a bottle (can't not drink champagne in a champagne bar) and it was lovely (an autumn blend).\n\nWe all thought the Cafe Bar was lovely and 'done' very well, with friendly staff but great service. Given demand at the Festival time, we weren't all squashed in and there was lots of room between tables. The setting was just stunning with the blue decor and given that I 'read' for a living, then I loved being surrounded by books. A great chance to see somewhere that is not normally open to the general public. \n\nNote: I'm also Gluten Free but everything (lobster, wedges and seafood minus bread) was ok for me to eat :)
