...go to Corniche and watch the bay. The beats you here isn't house music, but gipsy beatin her head on walls. Nice background for a romantic dinner. You can hear it throughout qatar!

No, sewrious advice now, get prepared... You aseated? fastened seatbelt? Here we go:
The Paloma in the Intercontinental is pretty nice if you look for some dirnks and music. If you want to have a bear and a quieter environment...Moevenpick. Party with loud music European club (good and cheap beers). Rydges is also a good place to have a drink and meet people. These are a view places to go for in the first week, until you make some friends and start discovering Doha on your own and determining your preferences! If you want a chilled evening, you can go to the park near Sheraton at the end of Corniche and have a picnic there! Many families do that, but I guess your question was aiming on the other alternatives!?

Anyway, have fun! and nod your head to gipsy's beat!
