A great casual place to party with friends is Cha-Cha-Cha in The Haight.
Cha-Cha-Cha is a really fun place but expect to spend some time waiting in the bar. It's pretty cheap and extremely popular. Known
for spicy Spanish style food, the dishes are served Tapas style to share with your friends. The Sangria is great too and the bar is very active. Since it's
really popular, try to come at an off time or with plenty of time to wait. They don't take telephone reservations. A great place, but more for the partying
group than the romantic candlelight dinner out. Andy's rating is "B+" for great food with long waits.
