There is a little restaurant in Park Slope called Helio's that is worth a visit. We were there last night and found the atmosphere charming and the food very good. It's on the ground floor level, lots of candles flickering and very friendly and cozy. The food is Greek, and I have to say the array of spreads were really fresh, top notch ingredients and perfectly seasoned. They serve a warm pita bread that is crisp on the outside and fluffy inside. It's great. We had a perfectly cooked, juicy hamburger, fabulous fries. Their spinach pie is nothing like the multi-layered, heavy oily things you find in many Greek places. Their's is a turnover, very crisp with fresh spinach and just enough cheese to make the filling tangy and creamy. It's excellent. The prices are reasonable and the service is friendly. It's really the embodiment of a neighborhood restaurant.
