How he does it is a mystery, but at LUNACY BLACK MARKET, Paul Luna is serving some of the tastiest food around at prices that might make you a little uncomfortable — and for the exact opposite reason most restaurant prices do: Luna's food is outrageously inexpensive. The Mediterranean small plates, such as sautéed mushrooms or roasted peppers with house-made ricotta, all hover around $3. Two people can easily eat and get stuffed for less than $25. The living room-like space and personality-driven service makes it that much more enjoyable. 231 Mitchell St. 404-736-6164. www.lunacyblackmarket.com.
