I lived in Dupont for 4 years and never made it to a variety of restaurants, including Pizzeria Paradiso and Johnny's Half Shell, mostly because I don't have the patience for an hour+ wait that I've heard they all entail on weekend nights. Now, a Virginia resident, I try to make the most of my dining exursions into the District. We're meeting friends for drinks in that area later tonight and I was thinking about finally giving Johnny's Half Shell a try for dinner beforehand. What is the wait going to be like around 7 or 7:30 on a Friday night? (for two) And, more importantly, is it worth it?
