Birmingham has always been my least favourite airport.
No 1 Lounge is good. Similar to but better than No 1 Gatwick, it has a big “complimentary” bar, a good range of “complimentary” food and a reasonable pay for menu.
Very comfortable seating, lounge chairs, sofas and a long dining table area. Very nice staff.
You pay £6 for a glass of champaign; it’s not compulsory …
This is a good 4*
