I have to assume that the only reason that L'Enfant has such a bad rap on here is because many of these reviews are on the older side. I think this place is great! It's still a bit under construction, so there are definitely still things to come, but the improvements that have been made over the past couple years are definitely worthy of a star upgrade, IMO.
I used to work right across D street from L'Enfant, and was a (very) frequent visitor for lunch. They main area is very close to the Metro entrance. They've got a good spread, too: Starbuck's, Potbelly's, Roti, Five Guys, Au Bon Pain, Crumbs Cupcakes, a pizza place, a self-serve froyo place (that does crepes and oatmeal, too!), and further into the plaza there's a McDonald's. There's also a standard-ish Korean deli-type place with a sushi bar. That's a lot of choices if you work in the area, especially when paired with the plethora of food trucks around the corner. Variety, people! I likes it.
I find the place to always be clean, and I kinda like the decor. There are these LCD columns that I find simply fascinating, admittedly. It does get a little craycray if you get there right during the lunch rush. My advice would be to get there by 11:45, or after 1:30 if you don't want to stand in line.
As for the non-food places, there's a CVS, a post office, a newsstand, and a couple of random boutiques (for those who do their last-minute gift shopping at lunch, I guess?). Again, not sure why this place has such low ratings, but I think it's a pretty great addition to this work-driven area! Just don't expect anything to be open if you come late or on a weekend. This is a place that caters solely to the working crowd, so everything's shut down by like 7 (if that).
