I liked the lounge in Brussels. It was large enough to accommodate the volume when I was there. The food was quite high quality (fruit salad with mango, papaya; a variety of cereals and yogurt, etc.). Not upto Wings in HKG or BA lounges in JFK/LHR but much better than AA lounges in Europe (though I'm OK with LAX flagship lounge). They did not have a wireless network, but you could use the wired LAN with DHCP or laptops provided by them.

I expect they'll provide much better lounges in the upgraded airports in India. I'll have to wait and see for that.
