Rob and I had dinner at Oola last night on Folsom Street. It's a fun bistro in SOMA with about 15 tables and a small cocktail bar.
The food and wine were both good, but the real stand out was the order of truffle french fries with parmesan cheese. Honestly, they were the best french fries I've ever had. Imagine the most perfect, hot McDonald's fries with truffle oil, a sprinkling of cheese and a hearty dash of salt.
Epicurious has a recipe if you are interested in trying truffle fries at home.
