My son is going to the senior prom and is looking for a place for dinner before. While the prom is in the city, East Bay for dinner would be easier. We live in El Cerrito. I was thinking of Rivoli but have never been - would it be appropriate for two couples in gowns and tuxes? From the website, the prices look fine. If not Rivoli, what would you suggest? Last year, they did Salute e Vita one event and Trader Vic's the other. TIA!
