There are live bands on tonight at Admiral's Club (located at the Ritz Carlton). Starts at 8pm, 30QR. It was pretty good when I went last time. Admiral's is a nice place to hang out at the weekend... pub atmosphere, by the water, not too rowdy :) Or Shehrazad at the Radisson (formerly Ramada) also has a pub feel, if you're looking for something casual and not too glitzy. The Belgian Cafe, as mentioned by ZuperZue, is also nice and relaxed.
