Have to say this was one of the best dining experiences I have had in quite some time in the NoVa area. And to find it so off the beaten path was especially surprising. The food was excellent, both my wife and I enjoyed our entrees, appetizers and dessert immensely. If you go, make sure you try the Tarte Tatin for dessert. It is not on their tray so you need to ask for it. El Manantial is pricier than the average neighborhood restaurant at $100 for a 3 course meal for 2 but well worth it for a fine meal out. Definitely plan on returning again. Note that if you make a reservation 24 hours in advance there are coupons on their website you can use to reduce the cost. ($20 of of 80 or more for dinner). We did not have a reservation and were seated immediately so don't let that stop you.
