Bisou is a Libyan restaurant.
I went to Bisou yesterday while headed to campus for a class. I was greeted by a friendly Libyan guy who explained the different foods to me. There is a very good selection of vegetarian food, from lentil soup to stuffed zucchini and bell peppers to samosa. I had the lentil soup and samosa. The food was delicious, but it could have been warmed up a bit more.
The prices are very reasonable. I recommend this restaurant to vegetarians and anyone looking for a light and hearty meal served quickly.
