I was in both last week and the spread in the DAA lounge was better than what Aer Lingus were offering. Both had similar booze offerings. The EI lounge is more comfortable/nicer aesthetically. I'm too used to the US at this point I guess, but really and truly EI should have a bar set up in the lounge. Similarly the coffee bar/cocktail bar set up in 51&G needs to be improved, there's too many pax in that lounge for a single attendant to handle - of course this is a DAA issue rather than an EI one.
Gotta say, the penny pinching is starting to show at EI in the J product. Really, really poor attention to detail across the board.
