I tried the "Best Sandwich" joint at 18th and K discussed in the thread below and I bascially agree with Steve: Much better than usual turkey sandwiches, and a great option for those working in the area, but not a destination spot (especially in light of the parking).
So where are the great sandwiches? I'll put aside here talk of Breadline, which has occasioned much debate on these boards. And I'll pass over hamburgers, because that's old hat, too (Colorado Kitchemn, Palena, 5 Guys, etc.). *Great* sandwiches I've eaten in recent months include:
-- A salami and goat cheese panini at 2 Amys
-- The Sloppy Joe at Colorado Kitchen (although Chef Clark's Friday lunches are apparently discontinued until fall)
-- The soft-shell sandwich served on Tuesdays (sometimes Wednesdays) at cf folks
-- Do barbacoa and lengua tacos at Taqueria Distrito Federal count?
Please add more sandwiches *worthy of a detour* . . .
