Clubs/Bars during the week?

[Westen]

We are leaving tomorrow for Vegas!!!
What are some good clubs or bars for Tues thru Fri? We are looking for upper 20's to 40's. Sport bars are great too!

I read that Studio 54 is good for Tues or Wed and you have to wear pants. Any other good clubs w/o a high cover charge?

I was wondering the same. me and 4 college friends..all 24 are going to vegas sept. 9. Most of the bars we have seen have $20 cover charge. Are there any good places maybe a little cheaper. What about once you get into these bars, how much are beers? thanks and a goodsite for club info is www.lasvegas.com, (http://www.lasvegas.com,) click on nightlife, has a lot of details.
