We're meeting up with a relative who cannot visit our condo (stairs), but would like to visit with our two kids, ages two and three. Is there someplace where we could get coffee and the kids could playa little or at least not be confined to a table ? Grounded in Alexandria (near Telegraph/Kings Hwy) has a small play area (books, blocks, train table) and is ideal, but not convenient, since the relative will be staying in Arlington (Ballston Metro) and won't have a car. Help?

Many thanks
