For an area like Urbana-Champaign, Soma provides a slightly more urban nightlife option. The dance space inside is small and has too many tables, but I have found the bouncers/management to be courteous enough.
The drinks are pricey and the cover can vary from 5-10 bucks but this is consistent with other options in the area. Enough people inside, even if some of the girls are the same-old-same-old. The crowd is generally 30s-40s and the club isn't really meant for undergrads.
Of course, it does not even begin to compare to the SFO/CHI night clubs that it so desperately tries to emulate (why do you need the velvet rope setup, for instance?).
Overall, I give it a 4/5 relative to other places in Chambana
