Maybe I just have bad luck when it comes to Soma, but it seems as if everytime I've been (a whopping two times), I was surrounded by men aged 30/40+.
The dance floor's fairly small and the sound system (though quite nice) was cranked up a bit too much for my liking. I much prefer the lounge; with its modern/metro setup, you almost forget you're in the middle of cornfields... almost.
It could just be the fact that I've been spoiled by the nightclubs in Chicago, but personally, I feel that they're trying too hard to be more than they really are, what with the (useless) velvet ropes, cover, and big ol' bouncers.
All in all, Soma probably wouldn't be my first choice the next time I feel like a night out with the girls, and there're definitely many bars around Champaign with a wide variety of drinks for a cheaper price, and no cover.
