Egypt Air has a unique and I find charming product.
Mind you, these experiences are on their short haul product.
The coupons they hand out for Star Golds are unique to them and a fantastic touch when there is no lounge. I had such a coupon when I passed through Sharm el Sheikh last year.
The domestic lounge is very small and dated compared to the international lounges. No Liquor as Sky Team 777 correctly pointed out.
I can do without the grog on the short domestic segments, but I'd find it a challenge on the longer haul if I was connecting through CAI!
